                    <li><code>region-mouseenter</code> - When the mouse moves over a region.  Callback will receive the <code>Region</code> object, and a <code>MouseEvent</code> object.</li>
                    <li><code>region-mouseleave</code> - When the mouse leaves a region.  Callback will receive the <code>Region</code> object, and a <code>MouseEvent</code> object.</li>

                <h4>Regions Plugin</h4>

                <p>Regions are visual overlays on waveform that can be used to play and
                    loop portions of audio. Regions can be dragged and resized.</p>

                <p>Visual customization is possible via CSS (using the selectors
                    <code>.wavesurfer-region</code> and <code>.wavesurfer-handle</code>).</p>

                <p>To enable the plugin, add the script <code>plugin/wavesurfer.regions.js</code> to
                    your page.</p>

                <p>After doing that, use <code>wavesurfer.addRegion()</code> to create Region objects.</p>

                <h5>Exposed Methods</h5>

                <ul>
                    <li><code>addRegion(options)</code> – Creates a region on the waveform. Returns a <code>Region</code> object.  See <a href="#region-options">Region Options</a>, <a href="#region-methods">Region Methods</a> and <a href="#region-events">Region Events</a> below.

                        <ul>
                            <li><strong>Note:</strong> You cannot add regions until the audio has finished loading, otherwise the <code>start:</code> and <code>end:</code> properties of the new region will be set to <code>0</code>, or an unexpected value.</li>
                    </ul></li>
                    <li><code>clearRegions()</code> – Removes all regions.</li>
                    <li><code>enableDragSelection(options)</code> – Lets you create regions by selecting.
                        areas of the waveform with mouse. <code>options</code> are Region objects' params (see <a href="#region-options">below</a>).</li>
		    <li><code>disableDragSelection()</code> - Disables ability to create regions.</li>
                </ul>
