Create language model

[MartinThoma]

A language model could vastly improve the classification performance.

To create one, I will parse

• the (english) Wikipedia for <math>...</math>
• the following LaTeX documents for align-environment, $...$, $$...$$ and \[...\], \(...\)
  • https://github.com/MartinThoma/LaTeX-examples/tree/master/documents/GeoTopo
  • https://github.com/MartinThoma/LaTeX-examples/tree/master/documents/Analysis%20I
  • https://github.com/MartinThoma/LaTeX-examples/tree/master/documents/Analysis%20II
