Detailed Description

Create LaTeX code for prettyprinting a mathematical expression (for example via MathJax)

Implementation of a Visitor, transforming an AST into a string giving LaTeX code for the expression.

The class in general does not generate the best possible LaTeX code, and needs more work to be used in a production setting.

Example:

$parser = new StdMathParser();
$f = $parser->parse('exp(2x)+xy');
printer = new LaTeXPrinter();
result = $f->accept($printer);    // Generates "e^{2x}+xy"

Note that surrounding $, $$ or \begin{equation}..\end{equation} has to be added manually.
