started on aggregations finally :)
all aggregation descriptors are now mapped
missed missing aggregations, go figure :/
most of the aggregations responses are mapped and the API is shaping up quite nicely
integration tests for all but nested aggregations
started on nested aggregation
Merge branch 'master' of github.com:Mpdreamz/NEST into feature/aggregations
added support for nested aggregation type
Merge pull request #491 from Mpdreamz/feature/aggregations

Aggregation support finally landed in NEST
