/**************************************************************************\
MODULE: GF2XVec
SUMMARY:
The class GF2XVec implements vectors of fixed-length GF2X's. You can
allocate a vector of GF2X's of a specified length, where the maximum
size of each GF2X is also specified. These parameters can be specified
either with a constructor, or with SetSize. It is an error to
try to re-size a vector of non-xero , or store a GF2X that doesn't fit.
The space can be released with "kill", and then you are free to call SetSize
again. If you want more flexible---but less efficient---vectors, use
vec_GF2X.
