ODL 0.3.0 Release Notes (2016-06-29)

This release marks the removal of odlpp from the core library. It has instead been moved to a separate library, odlcuda.

New features

To enable cuda backends for the odl spaces, an entry point 'odl.space' has been added where external libraries can hook in to add FnBase and NtuplesBase type spaces.
Add pytest fixtures 'fn_impl' and 'ntuple_impl' to the test config conf.py. These can now be accessed from any test.
Allow creation of general spaces using the fn, cn and rn methods. This functions now take an impl parameter which defaults to 'numpy' but with odlcuda installed it may also be set to 'cuda'. The old numpy specific Fn, Cn and Rn functions have been removed.

Moved all CUDA specfic code out of the library into odlcuda. This means that cu_ntuples.py and related files have been removed.
rename ntuples.py to npy_ntuples.py.
Added Numpy to the numy based spaces. They are now named NumpyFn and NumpyNtuples.
Prepended npy_ to all methods specific to ntuples such as weightings.
