  This is a simple list of all the names for "glyphs", or symbols, on the output graphs. This is used by the sums table to determine what symbol a straight-sum field can have on a graph.
</p>
<p>
  Nothing in this table should need to be modified. Adding things to this table will not add new glyph types; you have to edit the source to incgraph and simulgraph to do that.
</p>

<table class="database">

  <tr class="group"><td colspan=3><center>Fields</center></td></tr>

  <tr>
    <td>symbolname</td>
    <td>string</td>
    <td>The name of the glyph</td>
  </tr>
