Symbol Label (TBBSymbLabel)

The Symbol Label is intended for scientific and mathematical programs. 
Without it you either have to hope that the user understands x2 means x-squared or 
use several separate TLabels.

Its caption is split into sections by the $ character. The character following 
determines which font is used :

   $~    symbol
   $!    strong
   $>    small font as superscript
   $<    small font as subscript
   $     normal for any other character
