Query language

[jptmoore]

The current API is path based and only operates on a single stream of time series data. This API does not scale well or support joining together and carrying out operations on data from multiple time series streams. I useful addition would be a simple query language to give this type of flexibility.

[jptmoore]

Before attempting this I will extend the path API to handle multiple id's.

e.g. /ts/<id1, id2>/length

which would provide the length of the combined time series id1 and and id2

A first go at what some queries might look like that could map to tokens for verification:

post 42.0 to "sensor1" where "serial" is "A001" on host "foo"

get max from "sensor1","sensor2" where "serial" contains "A00" since "1h" on host "foo"

observe from "sensor1" where "serial" contains "A00" with last 100 on host "foo" for "60s"

delete from "sensor1","sensor2" from "1h" to "now" on host "foo"

@jptmoore might be worth moving this to the databox repo, not everyone follows this one.

I have many questions, lets discuss it on the next call.
