Merge pull request #311 from Morpho-lang/newlinalg

New linear algebra library. Includes replacement class for Matrix and a new ComplexMatrix class with extensive sharing of code and possible future expansion. Includes new functionality:

Matrix slicing now works with Tuples as well as Lists and Arrays.
Matrix indexing now supports negative indices to access the last element of a list.
Matrix and ComplexMatrix make better use of Tuples to return results, e.g. for dimensions(), eigenvalues() etc.
Matrix and ComplexMatrix support additional functionality, e.g. qr() and svd()
