v1.3.3

• Update to SuiteSparse 4.0.3 (new unary and binary ops, etc.)
• Added Windows support (without complex dtypes)
• Use NumPy's malloc/free, so Python knows memory usage of GraphBLAS objects
• Many improvements to import and export with SuiteSparse
  • Renamed fast_export to export and fast_import to import_any
  • Added other import methods such as Matrix.ss.import_csr
  • support zero-copy import and export if possible (user must opt in)
  • formats: csr, csc, hypercsr, hypercsc, bitmapr, bitmapc, fullr, fullc
• Matrix and Vector
  • allow contains expressions
    • 1 in v, True if there is a value at v[1]
    • (1, 2) in A, True if there is a value at A[1, 2]
  • iteration
    • Yields the indices of the structure
  • Add .wait() method
  • Add format attribute as e.g. my_matrix.ss.format
    • One of "csr", "hypercsc", "bitmapr", etc
• Scalar
  • Add .shape attribute (like Vector and Matrix, and like numpy scalars)
  • Able to cast to float and int
  • Allow things like __eq__ where .value is or computes a scalar
• Don't allow __eq__ or __bool__ where they don't make sense
