NF Schema v2.0.0

Version	Date	Author	Decision	Rationale
2.0.0	8/25/2021	RJA	Update milestoneReport definition.	To clarify that our "milestones" = GFF "progress reports".
2.0.0	9/16/2021	RJA	Added more granular assay terms for MRI (Magnetic Resonance Spectroscopy, Functional MRI, Conventional MRI). Conventional MRI replaces the previous term "MRI", thus this is a "major" update and is not backwards compatible. This will require remapping all "MRI" terms in the portal.	At data contributor request.
2.0.0	9/16/2021	RJA	Added "MRISequence" attribute with T1, T2, PD, and STIR sequences.	Help clarify conventional MRI data modalities.
2.0.0	9/16/2021	RJA	Changed "milestoneReport" to "progressReportNumber". Will need to remap term in main fileview.	At request of funding partner for clarity with their grantees.
