There's some bug with the testing harness where placing e.g.
from du import du
in nilmdb/utils/__init__.py doesn't quite work -- sometimes the
module "du" replaces the function "du". Not exactly sure why;
we work around that by just renaming files so they don't match
the imported names directly.
test_interval_speed is about O(n * log n), which is good -- but the
constants are high and it hits swap on a 4G machine for the 2**21
test. Hopefully cython helps!
tree.
This is currently hitting an issue where it's considering the
intersection of [0,1] and [1,2] to be [1,1]. It matches the
fully-closed definition of intervals, unlike before -- but might
cause issues. Need to consider whether test case is correct.

Doesn't actually merge them yet; need to change Interval
implementation to allow deletes.

On the big database, the server takes a few seconds to figure out the
interval intersections. Need to think about how to improve that --
the real key might be to start reducing the number of intervals we're
storing by combining them, potentially as they're inserted.

the TestIntervalSpeed versus the previous bisect version, but should
be better in general.

More work with nilmdb.stream_insert. Checks for overlap between
parser output and database intervals, and actually inserts the
data into pytables. Need to benchmark/figure out whether we can
use table.append rather than the row.append() nonsense -- it could
simplify things quite a bit.
Improve layout class and add tests to get more coverage. Better
error handling on invalid inputs (reports the reason for the error)
Replace layout.fillrow with layout.filltable, but turns out that we
can probably just remove it anyway.
Add nilmdb.Timer for simple timing tests
Move some duplicated test suite helper functions into a new file,
test_helper.py
Add class to test_interval.py to match the others

tolerance in equality comparisions, but it's a real pain to get all
the edge cases right, and it's not clear we actually need that
functionality at the moment. Skip it for now.
