Mathematical functions

[fabienrohrer]

For now, the formula sources are still into the TEX format in the webots/src/doc/formulas/ repository.

A better integration seems obviously required.

Several Javascript are doing mathematical text to HTML formula view conversion very well including:

• MathJax
• AsciiMath

MathJax is supposed to support TEX formulas, amongs other, which seems to be the shortest way to import our formulas.

Some code snippet are existing to integrate this into showdown:

@omichel After our discussion on Monday, I'm assigning this issue to you.

The proposed solution is the following:

• use MathML in our source files.
• include the MathJax Javascript from the cdn for the online version with the MML_HTMLorMML config, which mean input is in MathML format, output is in HTML or MathML if supported by the browser (Firefox supports MathML, Chrome doesn't).
• the offline version relies on WebKit which supports natively MathML.
• we can use online wysiwyg tools to generate the formulae in MathML format such as http://www.wiris.com/editor/demo/en/mathml-latex
