This is the first release of graphlib from the dagrejs organization.

Make preorder and postorder use successors for navigation when used with directed graphs. This is a backwards incompatible change. Previously neighbors was used for both directed and undirected graphs.

Add filterNodes to graph API.

Update to lodash 3.10.0

Bug fix for isAcyclic and findCycles for self loops.

Do not include minified JS in main content for bower.

graph.parent(x) always returns string node ids, similar to the behavior for node queries in other parts of the API.

• Rework setEdge to work with PhantomJS, which appears to not respect "use strict" in some contexts (#31).
