All these advances from politoscope prototype will be useful for the port and general refactoring:
  - removed legacy cortext localdb
  - new 'attrs to bins' logic (cf. scanClusters in parsing)
  - new 'attrs to colors' logic
  - new alt_colors rendering
  - new histogram variant: *daily* histograms
  - ! new simpler twitterAPI (directly with twitter's endpoints) !
  - useful debug logs for db.json loading and parseCustom
  - prepared parseCustom 'types' refactoring
  - getCurrentType function
