Expanded LU Decomposition Object

DESCRIPTION:
These are objects of class "expand.lu.Matrix" They represent the LU decomposition of a matrix.

GENERATION:
This class of objects is returned from the expand.lu.Matrix function to represent an LU decomposition.

STRUCTURE:
The following components must be included in a legitimate "expand.lu.Matrix" object:
l:
The unit lower triangular/trapezoidal factor.
u:
The upper triangular/trapezoidal factor.
permutation:
The row permutation applied to the original matrix in order to obtain the factorization.
