Store/data: add actions for aliasing and bundling, rename aggr. mutations, remove deprecated code, remove isUserDefined when creating aggregations, add tests for bundling (not passing), remove isUserDefined.

NodeSelection: add test UI for aggregations.
GraphNode: add bundle visuals, get bundle size from store.
NetworkGraph: tweak settings, renamed store actions.

Remove unused test
Added new random dataset for performance testing

Grouping/ungrouping algorithm seems finished, done minor refactor. Finished test "complex 1". Fix GraphNode: transition on removed node allowed user to interact with it, triggering error when getting node from store/data. #13

Grouping would like a refactor.
Also, the randomized test over big dataset is failing so there may be a corner case yet to be discovered. Not sure if bug, it may be also triggered by a bug in dataset.

Fix lint errors

WIP: better aggregation algorithm and dataset spec upgrade. New grouping with tests; added debug mode to graph which displays ids on nodes and links to better visualize the algorithm

Merge branch 'new-network-graph' of gitlab.fi.muni.cz:xrehacek/analysis-vis-prototype into new-network-graph

GraphLink: color sticky paws on hover (#2); switch left and ctrl click on nodes; store/data minor docs, add ungrouping hierarchy test - failing

This reverts commit 82a3a47b

Set new inAggregation for a link recursively, until last node in series of aggregations is found.

Store/data (#13): rewrite ungroup_nodes for basic scenarios; decompose group_nodes in insertLink; wip: remove_nodes, removing original entries sets isRemoved (changed dataset specs); remove gettter for new Id (should not be public)

Remove error in dataset-harry.

BaseIcon: compute radius.

Node/link: show alert when trying to render with invalid id.

Data/store: WIP modified ungrouping to handle different grouping order, working for 2 groups. Needs testing, possibly buggy (#13)

NetworkGraph: separate synchronization with store into methods; add saving of node positions; add handler for ungrouping; solve d3-force IDs
NodeDetailCard: add ungrouping option
Store/data: fix and test update nodes (needed deep merging); fix grouping; add action for ungrouping

Update packages, setup Jest for testing. Implement and test store/data/GROUP_NODES (#13) for general groups. Updated dataset format.
