FEATURES:

cuda
	is cuda support compiled in?
	NB: To check if there is also actually a usable GPU, use cudaAvailable()

mex_link
	is there support for the matlab command astra_mex_data3d('link')?

projectors_scaled_as_line_integrals
	This is set since all 2D and 3D, CPU and GPU projectors scale their outputs
	to approximate line integrals. (Previously, some 2D projectors were scaled
	as area integrals.)

fan_cone_BP_density_weighting_by_default
	This is set since fan beam and cone beam BP operations perform ray density
	weighting by default to more closely approximate the true mathematical adjoint.
	The DensityWeighting cuda3d projector option is removed.

unpadded_GPULink
	This is set since FP3D no longer silently fails with GPULink memory
	that is not padded to a multiple of 32 pixels

For future backward-incompatible changes, extra features will be added here
