Regulatory activity viewer: epigenome selection

[azangru]

Description

• When user starts interacting with regulatory activity viewer, he should see a list of pre-selected epigenomes (in a table), if it is provided by the backend
• User should be able to select other epigenomes. The selector (lists of checkboxes) appears as a modal dialog popup upon a click on the "Configure" button.
  • Checkboxes act as filters. Within a single list of checkboxes (a metadata dimension), selection of different checkboxes acts as a logical "OR" operator. Selecting checkboxes from different lists (different metadata dimensions) acts as a logical "AND" operator.
• The ticked selection criteria for epigenomes (filters) will appear in the sidebar, where they can be deleted.
• Selected epigenomes appear in the table at the bottom of the sceen
• Some of the metadata dimensions of an epigenome can be used to "combine" the epigenomes. Currently, this is done by clicking appropriate table column headings.

Other changes

• This PR also introduces a new component — CollapsibleSection, which seems to be better suited than Accordion for showing and hiding elements in the sidebar

This is a very rough approximation of the XD. Lots of things don't work quite as in the XD; but since the diff is already huge as it is, it will be useful to merge this PR with its current scope of changes.
