Error: Cannot call a class as a function when uglifying

See https://github.com/fielded/nav-integrated-national-dashboard/issues/101

Was fixed by #22

Have to figure out how to stop including external dependencies without getting this error. (the problem seems to be the build process, not the code)

The last build that seemed to work was the one for version 4.0.0.

After that any uglified build produces the error. May be related to a new version of some of the libraries used in the build process.

It works fine when not uglified.
