Matrix#determinant_bareiss

Private. Use Matrix#determinant

Returns the determinant of the matrix, using
Bareiss' multistep integer-preserving gaussian elimination.
It has the same computational cost order O(n^3) as standard Gaussian elimination.
Intermediate results are fraction free and of lower complexity.
A matrix of Integers will have thus intermediate results that are also Integers,
with smaller bignums (if any), while a matrix of Float will usually have
intermediate results with better precision.
