* initial revision
* Removed class members of Algorithm class
added update_objective
* initial version. Fix inline __idiv__
* First implementation of CompositeOperator/DataContainer
* removed __getitem__ added get_item added shape
* added CGLS
* working unit test, initial tomography test
* added reverse multiplication of operator with number
* added operators directory
* fixed typo
* added unittest for CompositeDataContainer
* fix TomoIdentity with scalar
* check numerical types from numpy
* add default stop criterion and run method
* add run method
* first working implementation of CGLS with CompositeOperator/DataContainer
notice problem with _rmul_ and _mul_ methods precedence with numpy.
* new Algorithm class and algorithms in separate files
Added new Algorithm class and derivatives in different files for
GradientDescent, CGLS, FBPD, FISTA
* added algorithms and restored CIL_VERSION env variable
* removed Algorithms.py
* modified run and renamed a few members/methods
* uses squared_norm
* renamed get_current_objective to get_last_objective
update_objective can be issued every N iteration, default 1.
fixed run method to run N iterations within the stop criterion.
* load class as module files
* force py line endings to LF
* updates
* call super __init__ as first thing
* unit tests are now to be found in test directory
unit tests are now split in several files in the directory test
* install algorithms module
* Implementation with Algorithm
* skip Reader tests
* unittest for linux
* commented not needed import Iterable
* removed explicit return from __init__
* remove composite operator file
