Reimplement graph tools to be able to port to cljs

[Rafik NACCACHE]

Currently we are using Loom to detect cycles in our tasks definition.

Despite all my efforts, I could not port loom to cljc, and that appeared to be too difficult a task for me.

Please head over to graph tools and see how to implement our cycle detection ?

the source is here:

https://github.com/turbopape/milestones/blob/master/src/milestones/graph_utilities.clj

and the two functions to implement are those required from loom.xyz namespaces.

Closed as Fixed. See version 0.2.0 that implements this.
