GlyGen Metadata upload

[ReneRanzinger]

As discussed in our meeting with @Mindyporterfield we should have an easy way to add GlyGen metadata to a collection.

1. Add a button "Add GlyGen metadata" button left of the add metadata button in edit collection (above the metadata table).
2. That button brings you to the "second" page of the metadata wizard with all the GlyGen metadata shown by default with their corresponding input fields. Metadata that has a multiple attribute have a "+" icon on the right that allows to add one more "row" of the same metadata. Non-mandatory rows or additional rows (even for mandatory rows) have a trash bin icon to delete the row.

In the following listing mandatory rows a in bold:

• Evidence
• Species
• Strain
• Tissue
• Cell line ID
• Disease
• Glycan dictionary term ID
• has_abundance
• has_expression
• Functional annotation/Keyword
• Variant (Fly, yeast, mouse)
• Organismal/cellular Phenotype
• Molecular Phenotype
• Contributor
• Comment
• Experimental technique

Please note: This listing makes assumptions:

• we only take biological data. Therefore species is required. If we allow to upload synthetic glycans that would have to be revised.
• we only take data resulting from experiments. If we allow to upload theoretical glycans that would have to be revised.
• we do allow upload of unpublished data. Therefore Evidence (PMID or DOID) is not required.

@jeet-vora will review the second part and confirm or suggest changes as part of #78

I have few comments that we can discuss in today's meeting.
