Nested display of child datasets in Explorer

[rsuchecki]

With growing number of datasets, we may consider restructuring how datasets are presented in Explorer.

Currently, we have:

or

+ Triticum_aestivum_IWGSC_RefSeq_v1.0
+ Triticum_aestivum_IWGSC_RefSeq_v1.0_90k_markers
+ Triticum_aestivum_IWGSC_RefSeq_v1.0_HC_genes
- Triticum_aestivum_IWGSC_RefSeq_v1.0_LC_genes
  1A
  1B

How about adding another level, such that

+ Triticum_aestivum_IWGSC_RefSeq_v1.0

expands to:

- Triticum_aestivum_IWGSC_RefSeq_v1.0
  + 90k_markers
  + HC_genes
  - LC_genes
    1A
    1B

This relates to our discussions on use of shortName for feature datasets.

Fully agree. This could be part of a more general capability of organising the explorer - for example, this would be "sort by parent", but you could also order by say, scope (so you see 1A, 2A, etc as entries, then the datasets containing them listed below that level), or filtered by giving a feature or list of features.
