 * @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.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,

  },
  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:

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>
