- NEW: added environment-modifying commands for font sizes: \c \\tiny ... \c \\normalsize ... \c \\Huge
- NEW: added environment-modifying commands for text color: \c {\\color{COL}...}
- NEW: added environment-modifying commands for text formatting: \c {\\bfseries...}, \c {\\itshape...}, \c {\\bf...}, \c {\\it...}, \c {\\sffamily...}, \c {\\ttfamily...}, ...
- REFACTORING: split up several .h/.cpp-files in nodes subdirectory

* text or nodes that require such a shift (e.g. \c \\nabla or \c \\int ):
