dendrogram interactions

[cornhundred]

Clicking the dendrogram should bring up the dendrogram tooltip, but allow the user to interact with it, e.g. stay visible permanently until closed again by clicking the dendrogram (or an x in the tooltip). I will probably need to create a separate class for this tooltip to prevent it from being hidden and to prevent additional tooltips from popping up while it is visible.

The tooltip needs:

• text selection box for rows/columns (e.g. comma separated)
• wrap around text for row and column cluster selection will instead have external widget view of selected terms see Observable examples
• run enrichment analysis via Enrichr
  • https://observablehq.com/@ismms-himc/clustergrammer-gl-and-enrichr
• export genes to Enrichr
• crop button to zoom into this section
  • will be useful for zooming into clusters of genes
  • will be useful for running front-end enrichment analysis on a cluster of genes

Setting up re-initialization (as well as destroying previous contexts) of visualization. Need to re-create network filtering as seen here
