The script adds {$$ ... $$} and {$...$} markups that display LaTeX-style math equations, the first form centers the equation, while the second generates the equation "inline".

Added in some rudimentary cross referencing. It is now possible to add \label{labelname} tags into display equations, which cause the equation to be numbered, and can then be referenced in the main text using an \eqref{labelname}. This is best explained with an example.

In Equation \eqref{eq:gamma} below I will define a famous special function.

{$$ \label{eq:gamma} \Gamma(z) = \int_0^{\infty} t^{z-1} e^{-t} dt $$}

Equation \eqref{eq:gamma} defines the {$\Gamma$} function, an extension of the factorial function.
