to_latex

https://github.com/cie/to_latex

Adds #to_latex to integers and strings. Works like html_safe in Rails, it escapes special characters as needed. Once converted, a string becomes a ToLatex::LatexString instance, with #latex? returning true, and never again will be escaped. You can concatenate any escaped or not escaped string to an escaped one, they get properly escaped. This gem powers texerb.
