This is a pretty big change that will render existing clients unable
to modify the database, but it's important that we use POST or PUT
instead of GET for anything that may change state, in case this
is ever put behind a cache.
These functions can now take an object or a type (class).
If given an object, they will wrap subsequent calls to that object.
If given a type, they will return an object that can be instantiated
to create a new object, and all calls including __init__ will be
covered by the serialization or thread verification.
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.
intervals are accessed, so it doesn't need to keep rebuilding them as
long as it's running.

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

handled by the HTTP server.
Add /stream/get_metadata HTTP request.
Fill out test_stream_metadata
Add runserver.py script to just run the server from the command line,
outside of the testing environment. Add necessary hooks within
nilmdb/server.py to allow this to happen.
Metadata operations get stream_id first and report error on missing
stream, instead of returning an empty dict.

Update layouts to include expected number of rows per day -- this is
used (as strongly suggested by the PyTables docs) to form a rough
estimate of the number of rows in a table during CreateTable.

layouts, rather than direct dict objects. This allows us to go
backwards and match the description of tables in the database with the
layouts defined within nilmdb.layout.
Fix some big issues with the nilmdb.server and startup errors like an
invalid port number. We have to catch os._exit and report the error
ourselves.
Add some timeouts and otherwise clean up tests.
Make NilmDB track and complain about files that weren't closed before
the object is destroyed.
Update stream_list and /stream/list to return the layout corresponding
to each table.
