kosz_hom1

Usage:
    <kosz_hom1 i m
The i-th koszul homology group of "m" is computed up
to degree 0, and displayed.
Thus the answer corresponds to the linear part of
the resolution at step k.
Parameters:
    i = integer >0
    m = module
Displayed value:
    the dimension of the ith koszul homology in degrees <= i
      (if m is generated in degrees >=0, then there is nothing
       of degree <0)
Setting i = 1 gives the vectorspace
of linear relations, etc.
The answer doesn't mean much unless the module is generated 
in degree >=0.
