/**
 * Serializes POJO models to UON (a notation for URL-encoded query parameter values).
 *
 * <h5 class='topic'>Media types</h5>
 * <p>
 * Handles <c>Accept</c> types:  <bc>text/uon</bc>
 * <p>
 * Produces <c>Content-Type</c> types:  <bc>text/uon</bc>
 *
 * <h5 class='topic'>Description</h5>
 * <p>
 * This serializer provides several serialization options.
 * Typically, one of the predefined DEFAULT serializers will be sufficient.
 * However, custom serializers can be constructed to fine-tune behavior.
 *
 * <p>
 * The following shows a sample object defined in Javascript:
 * <p class='bjson'>
 * 	{
 * 		id: 1,
 * 		name: <js>'John Smith'</js>,
 * 		uri: <js>'http://sample/addressBook/person/1'</js>,
 * 		addressBookUri: <js>'http://sample/addressBook'</js>,
 * 		birthDate: <js>'1946-08-12T00:00:00Z'</js>,
 * 		otherIds: <jk>null</jk>,
 * 		addresses: [
 * 			{
 * 				uri: <js>'http://sample/addressBook/address/1'</js>,
 * 				personUri: <js>'http://sample/addressBook/person/1'</js>,
 * 				id: 1,
 * 				street: <js>'100 Main Street'</js>,
 * 				city: <js>'Anywhereville'</js>,
 * 				state: <js>'NY'</js>,
 * 				zip: 12345,
 * 				isCurrent: <jk>true</jk>,
 * 			}
 * 		]
 * 	}
 * </p>
 *
 * <p>
 * Using the "strict" syntax defined in this document, the equivalent UON notation would be as follows:
 * <p class='buon'>
 * 	(
 * 		<ua>id</ua>=<un>1</un>,
 * 		<ua>name</ua>=<us>'John+Smith'</us>,
 * 		<ua>uri</ua>=<us>http://sample/addressBook/person/1</us>,
 * 		<ua>addressBookUri</ua>=<us>http://sample/addressBook</us>,
 * 		<ua>birthDate</ua>=<us>1946-08-12T00:00:00Z</us>,
