The Gene and Data type controls are dashboard
parameters that re-query four connector sources
(/api/ccle: distribution, heatmap, correlation, mutations). The Gene,
X-gene and Y-gene controls autocomplete gene symbols (type-ahead +
pick); the heatmap has its own comma-separated gene list; the correlation has four
selectors (X gene, X type, Y gene, Y type). Served live from ccle.sqlite.
