[aerogear-dev] AeroGear.js without jQuery Discussion

in the canary branch i started looking at removing jQuery from the UnifiedPush client code,  since it only uses jQuery.Ajax.  

https://github.com/aerogear/aerogear-js/tree/canary

i was thinking this would be a 2.0 thing,  but for this particular module/adapter/whatevs, i think we can update it before that since we marked  it "experimental"

in datamanager we have the IndexedDB and WebSQL adapters marked as experimental,  so we could do those, but since the other 2 adapters are not, we should probably wait.

Just want to see what the team thought about that, before i started to go cray-cray
