Ccpi forward backprojector (#77)
* added simple test for SinogramData
* initial version of processors
This contains a version of a simple normalization algorithm.
* added default pixel size = 1 (mm)
* Added FindCenter of rotation for parallel beam geometry
closes #5
* WIP for ccpi forward/backprojectors
* WIP
* Added Forward and Backprojectors from ccpi
added processor to pad acquisition data to center on center of rotation.
requires update of ccpi-reconstruction.
* Added simple_demo_ccpi.py
Currently there is a problem with the order of the axis after a projection/backprojection with the ccpi operator.
In the calculation of the PowerMethod there is a wrong order of the axis.
Possibly the creation of the data should be handled by the operator.
* fixed calculation of power method
* further work
* fixed the x_init for the FISTA example
* fixed ccpi FISTA demo
* Fix missing subset call for display
* Added create_image_data method to AstraOperatorSimple
* Stack direction 0, not 2, in TV
* Added finite different forward processor
* wip
* add io to setup.py
* wip
* comment out FiniteDifferentiator
* uniformed algorithm interface
Added some docstring.
Added parsing of opt.
* removed ccpi.io
* little changes
* fix setupCCPiGeometries
* added simple astra demo
* use minimal size for example
