facets (ie clusters and other searchable/colorable attributes) should work with bipartite case, but it meant factorizing facetsBinning() and updateValueFacets() from commit 71507331

we adapt the functions that currently need only one element (ie colors, legends) instead of adapting activetypes expression

this boolean array symbolizes for each node type if yes or no it is displayed, with effet also on edges)... It apparently replaced around 2015 the earlier convention with types A, B, AB... it is often used (symbolizing for each node type if yes or no it is active)... it was sometimes named states (very confusing with the other 'states' that record user interaction steps and that also contain info about these activetypes) or type (misleading singular)

old initListeners split in three: initGUIListeners and initSearchListeners that are run once at page load, and initSigmaListeners that is run for each new graph open from local file... also env function and CSS for the local graph file input

in other words we try to distinguish between what needs to be initialized once and what needs to be initialized each time we get new graph data... this use case wasn't covered before and will need some more re-designing, but it's convergent with modularising the app

fixed 'cluster_index' and 'clust_default' duplication, also fixed some remaining direct FA2 calls + minor others

(it was the original design in the 2014 versions and it provides more flexibility like future calling mainStartGraph from a fileinput instead of a remote file (see next commit))

gathered all conditional FA2 into one function using the switch itself as flag + added wait overlays on layout icons while they're running

'standalone mode' ie explorerjs.html can be just opened in a browser and will open a gexf from TW.Mainfile

faster NodeWeightFilter with the new index, harmonized calls and signatures for nodes and edges functions, TODO check lastFilter updating

grouped several init actions to Tinaweb.init() function and created a new index by sizes to avoid calling AlgorithmForSliders each time

fixed sigma port changes for bipartite states, and more casts removed for non numeric-ids

unclutter window scope of all parse-related and category-related vars + clarify confusion in using the word "reverse"

restored switch in main allowing API graph data input in json + started debugging types/categories + introduced the more generic variants of getUrlParam and prepareNodesRenderingProperties we did in comex2

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
