Detailed Description
LU solver implementation (TBCI::lu_decomp)LU decomposizes a TBCI::Matrix and solves the vector equation Ax = b
LU_xxxx operates on an already LU decomposed Matrix, whereas lu_xxxx does decompose it and then does * the requested action (eg. determinant calculation ...)
NOTE: the matrix passed as argument to lu_xxxx will be modified!
