Create the doxygen documentation

Molecuilder uses ​http://www.doxygen.org doxygen to create internal documentation of all classes and functions.

You create it by entering your build directory and typing

make doc

This will create html-pages, whose initial page is found under doc/html/index.html relative to molecuilder's root directory.

Note that you can search in the top right of the page for function names and so on.
