remove check on epsilon when inverting matrix with BK or with LU factorization.  The check is not needed (in fact is not in LAPACK) and it has been added for unknown reason in the CLHEP code which has been used for SMAtrix.  Checking that values are greater than zero is enough to detect singular matrices.
