====== CUTADD Command ======

CutAdd,<cut num>,<group num>,<elem 1>, … <elem N>\\
CutAdd,<cut num>,<group num>,RANGE,<elem start>,[elem end], [stride]

Both versions of this command allow the user to add elements to a cut. The first version of this command is intended for the user to enter a non-sequential list of elements from one group while the second command is intended for use with a continuous list of elements or a list with regular gaps between desired elements. This command will create the cut in memory if no cut has been defined for the cut num. 

  * cut num – number of the cut
  * group num – number of the group where the elements will be added
  * elem 1, elem N – element numbers to be added
  * elem start – first element to be added 
  * elem end - last element to be added  (default: start element number)
  * stride - increment to the next element (default: 1)
