The find module provides methods for working with objects.
for each registered object type (for example, User), a number of
methods will be available:
users_all([sort_criteria])
users_by_id( int identifier, [sort criteria] )
users( mapping criteria, [sort criteria])
users_by_query( string where clause )
users_by_alt(string alternate_id)
users_by_alternate(string alternate_id)
