Add \mathcal support in Math mode
This is supported in ipython markdown and is pretty standard in most TeX implementations. It is of great use for statistical or probabilityoriented decks, since we use cursive letters to denote distributions. (N= Gaussian, U=uniform...)
We just released support for font changing functions, like \mathcal.
More specifically we now support: \mathcal \mathbb \mathfrak \mathtt and \mathbf.

Hey. KaTeX – the library we're using to display math – is still relatively new and support for additional libraries are being added over time. Their most recent update from three weeks ago adds support for \mathcal and \mathbb among other things. We'll make sure to update to this soon so you can use those features in Slides.

Actually, several standard LaTeX libraries or tags are not included, like \mathbb, \begin{cases}..., which is really making it difficult to write convincing mathoriented decks.
