Additional message types

Currently, Amida's Node-only HL7 library does not provide full HL7 coverage. For a more complete implementation built on the Java HAPI HL7 implementation, see https://github.com/MatthewVita/node-hl7-complete. Keep in mind that running this library requires the use of Java 7.

The HAPI library exports two functions, jsToHl7 and hl7ToJs. If you want to use the HAPI library as a drop-in for this library, replace parseString(data) with hl7ToJs(data, callback), and replace serializeJSON(data, options) with jsToHl7(dataType, data, callback).
