Working prototype
Add a util module to provide convenience functions that'll make it
easier to access the data in the content that's returned in kairosdb.

Need to update the readme.
Support for graphite-style wildcards.  Only substring-wildcards aren't
supported (by which I mean globbing like foo.ab*.baz doesn't work, but
foo.*.baz does).
Working functions to query a metric in a graphite-friendly manner.
Provide graphite with time info and content - with the time info, the
content is assumed to have the appropriate intervals, so just send
back a list of floats along with the time info.
Fix the search to do something special for just a bare "*".

That's what graphite does when browsing top-level metrics.
graphite.read_absolute will now space the returned datapoints
correctly per what graphite-web expects.

It shouldn't happen, but if 2 datapoints fit within one time
interval, they will be averaged.
Fix big where not having recent enough data would cause an IndexError.
Add sphinx documentation.

Change the api for the reader's aggreattion and group_by functions to
reflect that they don't actually discriminate on the passed-in
metric_name - they were just going for [0].  So change the api to make
the caller explicitly pass in the part of the query they're interested
in.

Lots of documentation changes.

Almost ready to call this 0.0.1
Fix empty data sets.  https://github.com/pcn/pyKairosDB/issues/4
Merge pull request #5 from pcn/dev

Dev can now submit data to kairosdb from graphite, and request data as graphite wants it.
