Misc cleanup, docs, optional params
LA: update tests to modified optional signatures
LA: default to enable the computation of SVD vectors; cosmetics
LA: MILU(0) preconditioner (sparse optimized) by wo80, thanks!
LA: preconditioner more consistent naming
LA: flattening iterative solver namespaces
LA: Migrate sparse CSR format to more common row pointer convention
Cosmetics
LA: Make builder much more complete
LA: Fix arg validation bug in routine to copy a vector into a sub-row of a matrix
LA: F# matrix/vector creation now fully generic (hence all modules also)
LA: F# use 'SkipZeros' instead of cryptic 'nz' suffix
Resources: fix typo in histogram exception message.
LU: fix array length bug I've introduced into MILU(0) a few commits ago
LA: Add MILU(0) also for single, complex and complex32
Basic direct linear regression (simple, multiple, weighted, local)
Basic regression: multiple-response overloads (matrix instead of vector)
LA: fix return type of Norms to double (instead of T)
Distance: make vector implementations generic
Basic regression: cosmetics
