Great one!

@jingtang10 @ktarasenko I added a bunch of little improvements on documentation and code readability. I hope it helps.

is there anything blocking this from getting merged? we're going to add some test cases on top if this pr

[vitorpamplona]

hum... let me fix these conflicts.

[jingtang10]

Thanks Vitor!

[jingtang10]

I think we should do more work on documentation. How can this be used by developers? What advantages/disadvantages? Let's consider improving the github wiki regarding this?

For now this PR itself is fine.

thanks vitor

[vitorpamplona]

Thanks Jing!

I agree with the need to turn some of this into documentation, which frankly was what triggered this PR in the first place: people not knowing how to use the evaluator to compile and build CQL-based FHIR Libraries manually. Generating FHIRLibraries should be solved by appropriate tooling, but meanwhile, our documentation can fill the gap.

I also see good use of the testing platform to make sure the documentation is accurate and up-to-date.
