Moving cxxtest to Utilities, since it's used by a couple of pieces of code (ie. shared/DateTime and shared/io).
Remove byte-compiled Python (*.pyc) from repository & update gitignore so `git status` doesn't show untracked *.pyc files.
Bug fix: Dont forget to read the variables in!
Update reader for new multifluid variable naming convention.  Old format (rho_1_, rho_2_, etc) is deprecated.  New format is variable_.1, variable_.2, etc. (ie. rho_.1, rho_.2).
merge in master changes
more reasonable name for modules subdirectory
update versions file for new modules directory name
