This commit adds the ability to set string, integer, and boolean
values on bitmaps and profiles within Pilosa. Bitmap attributes
are automatically returned when making a `Bitmap()` call. Profile
attributes must be requested by setting `profile=true` in the
URL.
The function names have also been renamed to initial caps so that
the PQL query language can support math operations in the future.
This commit fixes the `pilosactl import` command to import data files
across an entire cluster of machines.
A `pilosactl config` command is also added to provide a default config.
This commit adds integration testing for the `cmd/pilosa` package.
It uses randomly generated `set()` data and verifies the data using `get()`
both immediately after the insert and after restart.
This commit refactors the pilosa codebase. It makes several major
changes:
* Removes bitmap handles
* Removes dispatch/hold/transport
* Removes etcd dependency
* Adds consistent hash ring for slice placement
* Refactors parser/lexer
* Adds strong typing to PQL AST
* Flattens package hierarchy
