Rename CareTeam.type to CareTeam.category for consistency with other resources. Many resources have a 'category' element and the description of CareTeam.type is consistent with other category elements.

For example, CarePlan.category had short description, "Type of plan". Observation.category is "Classification of type of observation". CareTeam.type definition is, "Type of team".

Current discussions about value set binding for CareTeam.type are focused on classification/categorization of a CareTeam, renaming 'type' to 'category' is more consistent and appropriate for this resource.
