ENH: CosmoTools Configuration Updates.

This commit slightly changes the format of the
configuration file and implements the corresponding
updates in the configuration file parser. Specifically,
the section for the parameters of each in situ algorithm
is now indicated by a line of the form "SECTION <algorithm>"
(as suggested by Hal) instead of "# SECTION <algorithm>",
which can be confused with a comment.
