public int getAlignMask() {

ByteSearch post search rule when a pattern is found. Used when a pattern must have a certain
alignment at an offset from the location the pattern matches. The alignment is
specified by the alignmask bits that must be zero.

  Normally alignOffset is 0, since most patterns will match at the address that must be aligned
  To align a match, use the following

 align to  2 = alignmask 0x1 - lower bit must be zero
 align to  4 = alignmask 0x3 - lower two bits must be zero
 align to  8 = alignmask 0x7 - lower three bits must be zero
 align to 16 = alignmask 0xF - lower four bits must be zero
 ....
 Other strange alignments could be specified, but most likely the above suffice.
@param alignOffset - bytes offset from pattern to check for alignment
@param alignmask - the mask where a 1 bit must be zero
