right after the merge of 4.14 release branch
+ manual fix on one line in:
* Arrangement_on_surface_2/include/CGAL/IO/Arr_text_formatter.h
* .travis/generate_travis.sh
Some formulas are shown as code due to the fact that the indentation of the start of the formula is 4 or more compared to the paragraph it is part of (handling of code sections has been improved from e.g. 1.8.13 to master).
the formula construct `\f$ .. \f$` should not be used when using e.g. the `equation` environment. With MathJax this works but in standard LaTeX an error is thrown (not yet the focus of CGAL, but might be of interest in the future / newer implementations of MathJax when more compatible).
