Two representations are offered: GF2mat_sparse for sparse GF(2) matrices and GF2mat for dense GF(2) matrices. Conversions between dense and sparse GF(2) are also possible.

Binary vectors are represented either via the bvec class (memory typically is not an issue here) or as n*1 (or 1*n) GF(2) matrix.

Note that the `bmat` class also provides some functionality for matrix algebra over GF(2) but this class is based on `Mat<>` which has a fundamentally different addressing mechanism and which is much less memory efficient (`Mat<>` uses one byte memory minimum per element).
