 How to add a new component model to cime.
-The cime to a component model is expected to be found in directory components/model/cime_config.  Each component will have xml file config_component.xml and will optionally have xml files config_compsets.xml, config_archive.xml, config_pes.xml, config_tests.xml.   It will have python interface scripts buildlib which provides the component build instructions and buildnml which will create the input arguments to the component model - there is also a file user_nl_xxx (where xxx is the component name) which allows the user to override input defaults on a case by case basis.  The cime_config directory may also have subdirectories SystemTests and testdefs which describe CIME based tests that are unique to the component model.
