- each module now has a version, eg IMP::get_module_version_info()
which is also returned by the various restraints of the module. The
python code checkes that loaded libraries have the expected version
numbers to try to provide better messages when errors in path link
result in linking against the wrong version of IMP.
- the various ::bounding_box() methods have been renamed
to ::get_bounding_box() to be more consistent with the other names.
