	16	* Provides default serialization of patients to clients. This class is used
	17	* when sending a list of patients to clients like mobile devices that may want
	18	* to collect patient data in for instance offline mode.
20	19	*
21		* For those who want a different serialization format for patients,
22		* just implement the SerializableData interface and specify the class
23		* using the openmrs global property {xforms.patientSerializer}.
24		* The jar containing this class can then be
25		* put under the webapps/openmrs/web-inf/lib folder.
26		* One of the reasons one could want a different serialization format
27		* is for performance by doing a more optimized and compact format.
28		* Onother reason i can foresee is for non java clients who may say
29		* want the patients in xml or any other format, because the default
30		* implementation assumes java clients.
