- the corresponding methods are not used and have been removed to fix
  this issue.

extend multi-slit language to support bitmap masks; Binary pbms not parsed correctly yet, working on it

IPPL/FFT cleanup:
- header added to file
- obsolete files removed
- line indentation fixed
- required functions and macros moved from c_utils.{c,h} moved to fftpack.cpp

renaming Collimator to CCollimator where C stands for cyclotron; all other collimators are implemented using FlexibleCollimator; This also fixes #224

first version of multi-slit/pepperpot/what ever aka flexible collimator. However way to slow to be practical

using affine transformation instead of coordinate transformation. This allows for shear and perspective operations (to be implemented).

first draft of 'MultiSlitLanguage'; action has to be developed yet; goal is to have a vector of basic shapes (rectangle and ellipse sofar) with corresponding coordinate transformations
