// LoadOnEntry:
// Load data into MatrixRow or Col dummy array under GetRow or GetCol
// StoreOnExit:
// Restore data to original matrix under RestoreRow or RestoreCol
// DirectPart:
// Load or restore only part directly stored; must be set with StoreOnExit
// Still have decide how to handle this with symmetric
// StoreHere:
// used in columns only - store data at supplied storage address;
// used for GetCol, NextCol & RestoreCol. No need to fill out zeros
// HaveStore:
// dummy array has been assigned (internal use only).
// For symmetric matrices, treat columns as rows unless StoreHere is set;
// then stick to columns as this will give better performance for doing
// inverses
// How components are used:
// Use rows wherever possible in preference to columns
// Columns without StoreHere are used in in-exact transpose, sum column,
// multiply a column vector, and maybe in future access to column,
// additional multiply functions, add transpose
// Columns with StoreHere are used in exact transpose (not symmetric matrices
// or vectors, load only)
// Columns with MatrixColX (Store to full column) are used in inverse and solve
// Functions required for each matrix class
