WIP. Fixed logging. Added log file and log level configuration specific to graphite_influxdb. Added logging calls for influxdb queries to ease debugging. Fixed bad imports causing cyclical dependency. Added config entries for new logging.
Added fake cache client for the case where cache is not configured in either graphite_api or django webapp. Added start/stop functions to fake statsd client. Modified get_leaves algorithm to be more efficient. find_leaves action is now ~4 times faster.
Moved imports outside __init__. This fixes #34. Added fake cache object in the case where cache is not configured. Modified compile_regex to be more general and correctly translate from wildcard query to regex pattern. Modified get_branches algorithm to be more efficient, using more efficient compiled regex for big speedup in branch finding and lower memory use.
Revert get_branches algorithm, simplify compile_regex
Bump version
