This re-implements the RectArray and Matrix classes:

  • Matrix is no longer derived from RectArray, but instead uses RectArray internally as storage.
  • RectArray is now implemented in terms of a continuous std::vector, rather that manually-allocated pointer-to-pointer
  • Internal implementations in both classes re-written to use STL algorithms and/or efficient iterators, as appropriate
  • General modernisation cleanups.

@tturocy
Refactor Matrix to have a RectArray but not be a RectArray.
18ba239 
This removes the inheritance of Matrix from RectArray, alongside changing
the internal representation of RectArray to be a continuous
std::vector of elements rather than a T ** with dodgy pointer arithmetic
for index range adjustments.
