Add must_close() decorator, use it in nilmdb

Warns at runtime if a class's close() method wasn't called before the
object was destroyed.

Refactor utility classes into nilmdb.utils subdir/namespace
...
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.

Remove compression.
...
Messes up extraction, since we random access for the timestamp binary
search. In the future, maybe switching to multiple tables (one for
timestamp, one for compressed data) would be smart.

Merging adjacent intervals is working now!
...
Adjust test expectations accordingly, since the number of intervals
they print out will now be smaller.

Some misc test additions, interval optimizations. Still need adjacency test

Use 'repr' instead of 'str' in Interval string representation.

Otherwise timestamps get truncated to 2 decimal places.

Speed tests.
...
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!
