Function: fir2long
FIR2LONG   Extend FIR window to LONG
  Usage:  g=fir2long(g,Llong);

  FIR2LONG(g,Llong) will extend the FIR window g to a length Llong*
  window by inserting zeros. Note that this is a slightly different
  behaviour than MIDDLEPAD.

  FIR2LONG can also be used to extend a FIR window to a longer FIR
  window, for instance in order to satisfy the usual requirement that the
  window length should be divisible by the number of channels.

  If the input to FIR2LONG is a cell, FIR2LONG will recurse into
  the cell array.
