 *  
 *  Implements the \cancel, \bcancel, \xcancel, and \cancelto macros.
 *  
 *  Usage:
 *  
 *      \cancel{math}            % strikeout math from lower left to upper right
 *      \bcancel{math}           % strikeout from upper left to lower right
 *      \xcancel{math}           % strikeout with an X
 *      \cancelto{value}{math}   % strikeout with arrow going to value
