In JavaScript, keys of object literals are always strings, and internal type conversions are performed. Now if we tell the compiler that keys are numbers, we get inconsistent types when iterating through keys. So instead we set the key type to string and do a type cast to make the compiler happy. Note that we could also do toString() instead of a type cast, but it would add a performance penalty (see http://jsperf.com/internal-type-conversion-vs-tostring-for-object-keys).

Run the test suite with PhantomJS
With PhantomJS installed, and assuming phantomjs is in the PATH:
$ phantomjs mocha-phantom.coffee ol.html
(Works with PhantomJS 1.6.1, untested with other versions.)
This command can also be run by doing ./build.py test at the root of ol3.
Make sure that the polvr web server is running (./build.py serve), otherwise
you will most likely see something like 0 specs, 0 failures in 0.001s..
Tip for TDD'ers: to make PhantomJS run the test suite continuously each time
a spec file is changed you can use nosier (http://pypi.python.org/pypi/nosier)
and do nosier -p test -p src "./build.py test".
