Issue 29 multi yaml add type part1

[amerharb]

in this part1 of issue 29 more or less this is just a refactor before actual solution

• add types
• save the source file (yaml file) for each message id where it comes from

Later in next PR: messages will be saved in its original file currently all saved in one file

Except for the tiny review finding above, it's all good. Thank you!
