Code stolen and convert to lua from https://en.wikipedia.org/wiki/LU_decomposition#C_code_examples I've not tested accuracy yet, but I'll see how it does soon.

Changed Pivot to Use Max

For some very strange reason, vector-to-matrix constructor doesn't work for vectors having more than 3 elements. Tail elements of the vector (starting with the 4-th) are silently rejected by the...

`matrix.copy()` implementation has dimension limits incorrectly swapped: `#m1[1]` and `#m1`, so it fails on attempt to copy any non-square matrix.

If `matrix:new` detects a vector, then it converts to a Nx1 matrix, instead of a 3x1 matrix.
