WIP: Removing confidence and agreement.
WIP: Much work done on removing confidence and changing potential parents screen for subsequent phases.
Finished removal of confidence, refactoring of view. Now more JS friendly (though the JS itself could use some more refactoring to separate dom and event handling stuff)
Cleaned up TODO, remoevd help messages, make IE8 friendly.
SVG graphic of the network, and an iterable view in the adminDash view.
Forgot to delete temp file after creating graphviz svg.
Updated README with reference to graphviz
Index out of bounds, due to the fact that admin users are not experts, thus the total experts is > 100%.
Added key to explain icons.
Merge branch 'master' into delete-via-arrow
