changed README to explain that we have no dependencies.
added node package json, vows-based test, using slightly obfuscated
model.json from cubes install.
linting fixes
removed console logs
use export(module) incantation so that just running "vows" runs the test
suite, instead of "node test/*.js".
added server_test.js, exercising server with mock ajax handler, and
execising full_cube() and Cell.slice(). Added bugfixes that tests
exposed. :)
removed all console.log entries entirely; changed Cell.slice() to accept
a cut object rather than assume point-cut-style arguments.
more lint corrections; prune test model of unneeded dimensions;
added model exercising tests.
added cut tests; bug fixes for cuts; added support for __null__ special
path value to represent nulls.
more cut-related unit tests; re-slicing on a dimension preserves that
dimension's place in the cut order.
more cut-related unit tests; cut and cell can now be parsed directly from
strings.
factor out cuts_from_string
