Method (no overloads)
Summary
The determinant of matrix , or null where the
elimination could not finish withinmaxWork or a division came
back inexact.
elimination could not finish within
back inexact.
Parameter "matrix"
Square, and modified in place — the caller owns it and must not need it
afterwards. Elimination is destructive, and copying here would hide the cost of the
one thing this exists to make cheap.

one thing this exists to make cheap.
Parameter "variableCount"
How many variables the entries are over, needed to build the zero and the one of the
same ring. Not derivable from the entries, since a matrix may be all constants.

Parameter "maxWork"
A ceiling on term-pair multiplications, charged before each multiplication
rather than after, so that the budget cannot be overshot by the one step that was
going to be the most expensive of them.
