includedPrimaryTypes property

Included primary Place type (e.g. "restaurant" or "gas_station") from https://developers.google.com/maps/documentation/places/web-service/place-types.

A place can only have a single primary type from the supported types table associated with it. Up to 50 types from Table A may be specified. If there are any conflicting primary types, i.e. a type appears in both included_primary_types and excluded_primary_types, an INVALID_ARGUMENT error is returned. If a Place type is specified with multiple type restrictions, only places that satisfy all of the restrictions are returned. For example, if we have {included_types = ["restaurant"], excluded_primary_types = ["restaurant"]}, the returned places provide "restaurant" related services but do not operate primarily as "restaurants".
