DATACUT is a function in graphic mode that selects and cuts a portion of
  data pack (DATA).

  After starting the main routine just type the following command at the
  prompt:
  DATACUT=datacut(DATA);
  [DATACUT LINES COLUMNS]=datacut(DATA);

  Input:
  DATA is the speckle data pack. Where DATA is a 3D matrix created grouping NTIMES 
       intensity matrices with NLIN lines and NCOL columns. When N=size(DATA), then
       N(1,1) represent NLIN and
       N(1,2) represent NCOL and
       N(1,3) represent NTIMES.

  Output:
  DATACUT Is the cut part of speckle data pack. Where DATACUT is a 3D matrix 
          created grouping NTIMES cut parts of DATA.
  LINES   [Optional] Is a vector with two elements, these are the first line
          and the last line in the cut of DATA.
  COLUMNS [Optional] Is a vector with two elements, these are the first column
          and the last column in the cut of DATA.
