Infer sample association from cell ID overlaps

[arteymix]

We can alleviate the burden of matching sample IDs with BioAssay name on curators by looking at overlap between cell IDs and building that association ourselves.

I think a simple metric to look at is the number of overlapping IDs between the cell IDs from the single-cell dimension and those found in the annotation file, and match those by the maximum value.

This is completed, I'll have the curator test it out tomorrow.
