LU Decomposition Object

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

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

METHODS:
The "lu.Matrix" class of objects has methods for the following generic functions: det, expand, facmul, rcond, solve

STRUCTURE:
The following component must be included in a legitimate "lu.Matrix" object:
factors:
a matrix in which the triangular factors are stored.
pivot:
the row permutation applied to the original matrix to achieve LU decomposition.
