---Added a list of graphs which interacts with the new latex writing
function in CR. New graphs can easily be added to the list. The function
latex_graphs needs to return an array of graphkits and latex code blocks
describing the graphs. See CR and GS2CRMOD functions for more info.
There is no unit test yet, not clear whether this function needs to be
enabled since not all machines have pdflatex etc installed.
Version bump to 0.11.62
Regenerate gemspec for version 0.11.62
