SystemState now integrates the currently highlighted neighbors and relations under .selectionRels property + with this we can optimize deselectNodes (replaces both highlightSelectedNodesand greyEverything and enhances cancelSelection)

start integrating neighbors in systemstate (objective: avoid loops on full graph when deselecting with greyEverything) + removed grey flag which was now always == (!active && !highlight)

clarified changeType steps and conditions + added possibility to come back from 'both types active' state

the new variant pushState will append new states itself + SystemState becomes an accessor to TW.states[-1] + start simplifying changeType

via user-configuration of a ranking metric to choose k best labels from the cluster's node set (available from the facet-options dialog box)

NB: still need to rm old nodes1 nodes2

as usual we don't touch the sigma or plugin code, but simply restrict event propagation (plugin's handlers are on body, but events come from sigma container first)

optional: can be set in conf with 'moreLabelsUnderArea' flag, uses our new functions circleGetAreaNodes() and redrawNodesInHoverLayer()

added for node rendering with various cases (active/neighbor/normal/grey), then made the labels renderer call the node renderer

(it fixes the black color init cases)

show nbClasses and nbNodes side by side, don't count N/A class in nbClasses if empty, rename vars to be clearer

translations for the color menu can be specified in TW.conf.facetOptions + make clusterColoring work for string-labeled clusters + allow user to choose if colors are randomized each time

assumed that source gexf file was equivalent to having a 'name' node attribute, which is not the case in specifications?

global var selections removed and stored inside SystemState + transformed into an array everywhere (was inconsistent) + fixed changeType selection materialization ; possible TODOES: better setState function, possible integration of opposite side neighbors in SystemState too
