/**
 * Creates map, draws paths, binds events.
 * @constructor
 * @param {Object} params Parameters to initialize map with.
 * @param {String} params.map Name of the map in the format <code>territory_proj_lang</code> where <code>territory</code> is a unique code or name of the territory which the map represents (ISO 3166 standard is used where possible), <code>proj</code> is a name of projection used to generate representation of the map on the plane (projections are named according to the conventions of proj4 utility) and <code>lang</code> is a code of the language, used for the names of regions.
 * @param {String} params.backgroundColor Background color of the map in CSS format.
 * @param {Boolean} params.zoomOnScroll When set to true map could be zoomed using mouse scroll. Default value is <code>true</code>.
 * @param {Boolean} params.zoomOnScrollSpeed Mouse scroll speed. Number from 1 to 10. Default value is <code>3</code>.
 * @param {Boolean} params.panOnDrag When set to true, the map pans when being dragged. Default value is <code>true</code>.
 * @param {Number} params.zoomMax Indicates the maximum zoom ratio which could be reached zooming the map. Default value is <code>8</code>.
 * @param {Number} params.zoomMin Indicates the minimum zoom ratio which could be reached zooming the map. Default value is <code>1</code>.
 * @param {Number} params.zoomStep Indicates the multiplier used to zoom map with +/- buttons. Default value is <code>1.6</code>.
 * @param {Boolean} params.zoomAnimate Indicates whether or not to animate changing of map zoom with zoom buttons.
 * @param {Boolean} params.regionsSelectable When set to true regions of the map could be selected. Default value is <code>false</code>.
 * @param {Boolean} params.regionsSelectableOne Allow only one region to be selected at the moment. Default value is <code>false</code>.
 * @param {Boolean} params.markersSelectable When set to true markers on the map could be selected. Default value is <code>false</code>.
 * @param {Boolean} params.markersSelectableOne Allow only one marker to be selected at the moment. Default value is <code>false</code>.
 * @param {Object} params.regionStyle Set the styles for the map's regions. Each region or marker has four states: <code>initial</code> (default state), <code>hover</code> (when the mouse cursor is over the region or marker), <code>selected</code> (when region or marker is selected), <code>selectedHover</code> (when the mouse cursor is over the region or marker and it's selected simultaneously). Styles could be set for each of this states. Default value for that parameter is:
<pre>{
  initial: {
    fill: 'white',
    "fill-opacity": 1,
    stroke: 'none',
    "stroke-width": 0,
    "stroke-opacity": 1
  },
  hover: {
    "fill-opacity": 0.8,
    cursor: 'pointer'
  },
  selected: {
    fill: 'yellow'
  },
  selectedHover: {
  }
}</pre>
* @param {Object} params.regionLabelStyle Set the styles for the regions' labels. Each region or marker has four states: <code>initial</code> (default state), <code>hover</code> (when the mouse cursor is over the region or marker), <code>selected</code> (when region or marker is selected), <code>selectedHover</code> (when the mouse cursor is over the region or marker and it's selected simultaneously). Styles could be set for each of this states. Default value for that parameter is:
<pre>{
  initial: {
    'font-family': 'Verdana',
    'font-size': '12',
    'font-weight': 'bold',
    cursor: 'default',
    fill: 'black'
  },
  hover: {
    cursor: 'pointer'
  }
}</pre>
 * @param {Object} params.markerStyle Set the styles for the map's markers. Any parameter suitable for <code>regionStyle</code> could be used as well as numeric parameter <code>r</code> to set the marker's radius. Default value for that parameter is:
<pre>{
  initial: {
    fill: 'grey',
    stroke: '#505050',
    "fill-opacity": 1,
    "stroke-width": 1,
    "stroke-opacity": 1,
    r: 5
  },
  hover: {
    stroke: 'black',
    "stroke-width": 2,
    cursor: 'pointer'
  },
  selected: {
    fill: 'blue'
  },
  selectedHover: {
  }
}</pre>
 * @param {Object} params.markerLabelStyle Set the styles for the markers' labels. Default value for that parameter is:
<pre>{
  initial: {
    'font-family': 'Verdana',
    'font-size': '12',
    'font-weight': 'bold',
    cursor: 'default',
    fill: 'black'
  },
  hover: {
    cursor: 'pointer'
  }
}</pre>
 * @param {Object|Array} params.markers Set of markers to add to the map during initialization. In case of array is provided, codes of markers will be set as string representations of array indexes. Each marker is represented by <code>latLng</code> (array of two numeric values), <code>name</code> (string which will be show on marker's tip) and any marker styles.
 * @param {Object} params.series Object with two keys: <code>markers</code> and <code>regions</code>. Each of which is an array of series configs to be applied to the respective map elements. See <a href="jvm.DataSeries.html">DataSeries</a> description for a list of parameters available.
 * @param {Object|String} params.focusOn This parameter sets the initial position and scale of the map viewport. See <code>setFocus</code> docuemntation for possible parameters.
 * @param {Object} params.labels Defines parameters for rendering static labels. Object could contain two keys: <code>regions</code> and <code>markers</code>. Each key value defines configuration object with the following possible options:
<ul>
  <li><code>render {Function}</code> - defines method for converting region code or marker index to actual label value.</li>
  <li><code>offsets {Object|Function}</code> - provides method or object which could be used to define label offset by region code or marker index.</li>
</ul>
<b>Plase note: static labels feature is not supported in Internet Explorer 8 and below.</b>
 * @param {Array|Object|String} params.selectedRegions Set initially selected regions.
 * @param {Array|Object|String} params.selectedMarkers Set initially selected markers.
 * @param {Function} params.onRegionTipShow <code>(Event e, Object tip, String code)</code> Will be called right before the region tip is going to be shown.
 * @param {Function} params.onRegionOver <code>(Event e, String code)</code> Will be called on region mouse over event.
 * @param {Function} params.onRegionOut <code>(Event e, String code)</code> Will be called on region mouse out event.
 * @param {Function} params.onRegionClick <code>(Event e, String code)</code> Will be called on region click event.
 * @param {Function} params.onRegionSelected <code>(Event e, String code, Boolean isSelected, Array selectedRegions)</code> Will be called when region is (de)selected. <code>isSelected</code> parameter of the callback indicates whether region is selected or not. <code>selectedRegions</code> contains codes of all currently selected regions.
 * @param {Function} params.onMarkerTipShow <code>(Event e, Object tip, String code)</code> Will be called right before the marker tip is going to be shown.
 * @param {Function} params.onMarkerOver <code>(Event e, String code)</code> Will be called on marker mouse over event.
 * @param {Function} params.onMarkerOut <code>(Event e, String code)</code> Will be called on marker mouse out event.
 * @param {Function} params.onMarkerClick <code>(Event e, String code)</code> Will be called on marker click event.
 * @param {Function} params.onMarkerSelected <code>(Event e, String code, Boolean isSelected, Array selectedMarkers)</code> Will be called when marker is (de)selected. <code>isSelected</code> parameter of the callback indicates whether marker is selected or not. <code>selectedMarkers</code> contains codes of all currently selected markers.
 * @param {Function} params.onViewportChange <code>(Event e, Number scale)</code> Triggered when the map's viewport is changed (map was panned or zoomed).
