What is an HL7-Message? Can that info be included (or linked to) in the README?

[MartinEnders]

I cited from the FAQ from hl7.org and put it in the README.md file (on both Projects hl7-parser and hl7-client):

The HL7 Version 2 Messaging Standard — Application Protocol for Electronic Data Exchange in Healthcare Environments — is considered to be the workhorse of data exchange in healthcare and is the most widely implemented standard for healthcare information in the world.
