/*
 * ENTITY_SPECS: defines the entities we are dealing with. The first one is the primary entity; the others are
 *              subentities.
 * entity_name: name for this entity type. Used internal for an individual entity. Used externally as the name for
 *              individual units of this entity
 * group_name:  plural name for the group. Used internal for aggregating into groups and for external output.
 * keyId:       The field in the FIELD_SPECS that is a unique identifier. Could be blank for those entity types
 *              that are not really considered individual entities, but are more of a list of grouped attributes
 * join:        The SQL join statement that will bring in the data for this entity type when connected with the
 *              primary entity's JOIN statement. Note: these must be able to be used in aggregate with all the
 *              other joins in the ENTITY_SPECS, so any duplicate joins to the same table must use a unique
 *              alias for that table.
 * default_fields:  Only needed for the primary entity. Lists the fields that will be included in the results
 *              if API call does not include an explicit list of fields to include.
