Updated comments in Models
Converted doxygen style comments to reStructuredText style in the files
 found in Cura/cura/Model directory recursively  using the script
dox_2_rst.py (provided in the Uranium repo). Comments were manually
 checked and changed if needed.

 Note: dox_2rst.py struggles with decorated functions.
