more updates to HGAPI and Alter, this time to enable __begin__ and __load__ on alter-templates as surrogates for the same thing in models previously. also updated tiles in summary variations and finally made the css classes applied to body on sucess of HGAPI be set whether or not data was actually loaded - it indicates that opportunity to load has passed and so makes the data-when clause easier to write when one of the types of data (provider or facility) is conditional.
updates to bring summary variations up to all tiles working; small bugfixes to Alter and HGAPI (moved all HGAPI calls to model and had to change namespace of model to Alter.Model, as it should be)
