LayerManagement: Added script to generate specification document

Since the doxygen generator can not be configured to leave out some parts of the
documentation (e.g. Class Documentation), a script was created to create
the desired documentation. The Script:
- create the html and latex documentation using doxygen
- patch the latex files to exclude the unnecessary sections of the document
- create the pdf version with correct file name
