* @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:

* @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>
