These methods convert yuima-class

yuima.model-class
, yuima.carma-class
or yuima.cogarch-class
objects to character vectors with
LaTeX markup.

This method tries to convert a formal description of the model slot
of the yuima object into a LaTeX formula.
This is just a simple proof of concept and probably further LaTex
manipulations for use in papers.
Copy and paste of the output of toLatex
into a real LaTeX file
should do the job.
