Refactored mixins into utils
ES2015 module exports
ES2015-style imports
WIP Fixing tests
Fixes tests after es2015 code migrations.
We we're require()ing an ES2015 module[1]. Have to make sure you account
for the .default in this case.
[1] We had to use ES5 `require` in Jest:
(https://github.com/babel/babel-jest/issues/16)
* always set updated topology object when received
* track whether route was set on initial load
* removed connection count from status bar (was not deemed important)
* fixed issue where topology option changes did not affect details pane
* only show filtered nodes when count > 0
* clear nodes graph when empty topology is loaded
* also prevent JS error if nodes are hovered over that should be gone
* fixed options sync issue between graph and status bar
* implemented topology options with immutable DS
- fix nodes reset after topology option change
- set topology on click
- explicitly set default topology options
- set default topo options when topos are received
- prevent JS error on too many nodes layout abort
