On group comparison view add table for categorical values

[inodb]

We introduced a table with summary stats for continuous values in this PR:

cBioPortal/cbioportal-frontend#4924

It would be great if we can add a similar table for categorical values:

See e.g. this link:

https://www.cbioportal.org/comparison/clinical?sessionId=5cf89323e4b0ab413787436c

The table could show the number of times a particular value occurs for each category across the groups

Hi @inodb , I'm new on the project. I see no one started this one. So I'll try to do it :) Hopefully within a week
