Solving
These helper methods are used during the factorization process. The solve*-methods solve lower and upper triangular systems from the left or from the right, respectively The methods with '2' in the end solve two systems at the same time. The methods with "Eps" in the end consider elements smaller then the passed epsilon as zero.

Performs the Forrest-Tomlin update of the LU factorization.

BH: I suppose this is implemented as described in UH Suhl, LM Suhl: A fast LU update for linear programming, Annals of OR 43, p. 33-47, 1993.

Parameters

p_col	Index of basis column to replace.
p_work	Dense vector to substitute in the basis.
num	Number of nonzeros in vector represented by p_work.
nonz	Indices of nonzero elements in vector p_work.

The parameters num and nonz are used for the following optimization: If both are nonzero, indices of the nonzero elements provided in nonz (num giving their number) allow to access only those nonzero entries. Otherwise we have to go through the entire dense vector element by element.

After copying p_work into U, p_work is used to expand the row r, which is needed to restore the triangular structure of U.

Also num and nonz are used to maintain a heap if there are only very few nonzeros to be eliminated. This is plainly wrong if the method is called with nonz==0, see todo at the corresponding place below.

Exceptions

SPxStatusException if the loaded matrix is singular

Todo:: Use an extra member variable as a buffer for working with the dense row instead of misusing p_work. I think that should be as efficient and much cleaner.

The following assert is obviously violated if this method is called with nonzero==0.

Todo:: Use an extra member variable as a buffer for the heap instead of misusing nonz and num. The method enQueueMin() seems to sort the nonzeros or something, for which it only needs some empty vector of size num.
