Fix assures a series is in quantized form: all points are nicely aligned (quantized) and padded with nulls in case there's gaps in data graphite does this quantization before storing, we may want to do that as well at some point note: values are quantized to the right because we can't lie about the future: e.g.

NewReqsPlan generates a ReqsPlan based on the provided ReqMap.

GroupData embodies a set of requests broken down by whether requests are MDP-optimizable, and by archivesID.

ReqMap is a map of requests of data, it has single requests for which no pre-normalization effort will be performed, and requests that can be pre-normalized together to the same resolution, bundled by their PNGroup.

ReqsPlan holds requests that have been planned, broken down by PNGroup and MDP-optimizability.

Requests indexed by their ArchivesID.
