Added additional input parameter for ignoring edges that are not able to lead to paths into the shadow region.

Removed CreateImageReceiver() and added filter for edges and faces. If the main face or the opposite face is the same face as the face, where the reflection occurs, the combination wont lead to valid paths.

Decreased the number of iterations for the calculation of the aperture point to 5 and in CombinatedModelTest, the number of reflections and diffractions are now calculated via the member functions of CPropagationPath

Removing lonely line in simple urban environment sketchup file and removing unrequired lines in test

Bugfix: In the propagation tree, an invalid shape child set the parent to null even if the parent was valid.

Added calculation of diffraction aperture points as well as the image source construction of secondary sources created by the edges.

Added construction functions for image sources, image edges and image receiver as well as functions for the creation of the propagation lists

Added Files for base propagation path simulation classes(implementation is wip) and renamed urban propagation path classes for easier distinguishing the files in a file editor.

Changed the name of the file to be tested to a checked-in one.
