       Arguments:

       <b>&lt;randomlabel&gt;</b> shows a specified image with
       images or text labels randomly assigned to a set of
       specific locations, those locations may also have values
       assigned to them. There is a hash generated conating the
       mapping of labels to locations, labels to values, and
       locations to values. Example:
       <pre>
    &lt;randomlabel bgimg=&quot;URL&quot; width=&quot;12&quot; height=&quot;45&quot; texwidth=&quot;50&quot;&gt;
       &lt;labelgroup name=&quot;GroupOne&quot; type=&quot;image&quot;&gt;
         &lt;location x=&quot;123&quot; y=&quot;456&quot; value=&quot;10&quot; /&gt;
         &lt;location x=&quot;321&quot; y=&quot;654&quot; value=&quot;20&quot; /&gt;
         &lt;location x=&quot;213&quot; y=&quot;546&quot; value=&quot;13&quot; /&gt;
         &lt;label description=&quot;TEXT-1&quot;&gt;IMG-URL&lt;/label&gt;
         &lt;label description=&quot;TEXT-2&quot;&gt;IMG-URL&lt;/label&gt;
         &lt;label description=&quot;TEXT-3&quot;&gt;IMG-URL&lt;/label&gt;
       &lt;/labelgroup&gt;
       &lt;labelgroup name=&quot;GroupTwo&quot; type=&quot;text&quot;&gt;
         &lt;location x=&quot;12&quot; y=&quot;45&quot; /&gt;
         &lt;location x=&quot;32&quot; y=&quot;65&quot; /&gt;
         &lt;location x=&quot;21&quot; y=&quot;54&quot; /&gt;
         &lt;label&gt;TEXT-1&lt;/label&gt;
         &lt;label&gt;TEXT-2&lt;/label&gt;
         &lt;label&gt;TEXT-3&lt;/label&gt;
       &lt;/labelgroup&gt;
      &lt;/randomlabel&gt;
       </pre>
       Arguments:
       <ul>
         <li>
    <i>bgimg</i> either a fully qualified URL for an
    external image, or a loncapa resource, it supports
    relative references (../images/apicture.gif), the
    image must either be a GIF or JPEG
         </li>
         <li>
    <i>width</i> the width of the image in pixels
         </li>
         <li>
    <i>height</i> the height of the image in pixels
         </li>
         <li>
    <i>texwidth</i> the width of the image in millimeters
         </li>
       </ul>
       Internal tags:
       <ul>
         <li>
    <b>&lt;labelgroup&gt;</b> 1 required, multiple
    allowed. Declares a group of locations and labels
    associated with them.  <br />Arguments:
    <ul>
     <li>
       <i>name</i> this is the name of the group, a hash
       with this name will be generated holding the
       mappings for later use in the problem. For each
       location a value will be set for which label is
       there, (EX. $hash{'1'}="TEXT-2"). For locations
       with values the hash will contain 2 items, a
       location to value mapping ($hash{'value_1'}=10),
       and a label to value mapping
       ($hash{'labelvalue_2'}=10). For all image style of
       labels there will also be a label description to
       label URL mapping ($hash{'image_2'}=IMG-URL). Also
       the entry 'numlocations will be set to the total
       number of locations that exist.
       (Note that locations and labels start counting from 1.)
     </li>
     <li>
       <i>type</i> the type of labels in this group,
       either 'image' or 'text'
     </li>
    </ul>

         <li>
    <b>&lt;location&gt;</b> declares a location on the
    image that a label should appear at <br />Arguments:
    <ul>
     <li>
       <i>x</i> the x value of the location in pixels 
     </li>
     <li>
       <i>y</i> the y value of the location in pixels 
     </li>
     <li>
       <i>value</i> a scalar value to associate at this
       location (optional)
     </li>
    </ul>
         </li>
         <li>
    <b>&lt;label&gt;</b> declaration of a label, if this
    is a text type labelgroup the internal text should be
    the text of the label (HTML is not currently
    supported), if this is an image type of label the
    internal text must be a LON-CAPA resource
    specification, and the description filed must be set.
    <br />Arguments:
    <ul>
     <li>
       <i>description</i> a required field for image
       labels, it will be used when setting values in the
       hash.
