rank(Tensor) erroneously called Tensor::size
Range::includes(index) and includes(ordinal) now work correctly.
Moved basic checks from index_traits to type_traits
Resolved ambiguity in Tensor(Range,Storage) constructors.
Updated ger_impl.h
Switched from postfix to prefix form for begin, end, extent, and rank.
Updated ger_impl.h
Updated permute; switched from postfix to prefix form for begin, end, extent, and rank.
Minor comment fix.
Updated “annotated” contract.
Updated contract.h; switched from postfix to prefix form for begin, end, extent, and rank.
Removed obsolete test_nditer_str.C
Renamed *_test to test_*
Due to bugs in trunk of TiledArray (but not in expressions branch) can’t compute expressions with btas::Tensor as Tiles.
