Tim Schaub 4ad8f2118c Adding paging and cluster strategies. The paging strategy intercepts a batch of features bound for the layer and caches them, giving the layer one page at a time. The cluster strategy intercepts a batch of features and groups proximate features as clusters - giving the clusters to the layer instead. Thanks for the careful review Erik. r=euzuro (see #1606). ...

BBOX.js

Adding a BBOX strategy. This triggers requests for data within a bounding box. When the map bounds invalidate previous data bounds, another request is issued. Reads are triggered with a spatial filter, and protocols that understand how to deal with filters may serialize the filter to request a subset of the data collection. The HTTP protocol understands one filter - the bbox filter. So the BBOX strategy can be used in conjunction with the HTTP protocol to request data via http in a bounding box. Thanks for the collaboration and tests Eric. r=elemoine,crschmidt (#1731)

The cluster strategy intercepts a batch of features and groups proximate features as clusters - giving the clusters to the layer instead. Thanks for the careful review Erik. r=euzuro (see #1606).
