Are you getting a totally unhelpful message from Angular saying it has a problem loading a module?

check-angular-module-dependencies.js

/**
 * There's times that Angular reports errors similar to this one:
 *
 *     Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.6.2/$injector/modulerr?p0=...
 *
 * The link doesn't explain the module tree that's being loaded nor really
 * where the problem resides.  :-(
 *
 * So I have had a bugger of a time figuring out what dependency fails and
 * exactly how that module is required.  This function will do that search
 * for you. Simply open up the browser's console, copy and paste in the function,
 * then call it with the name of the module you expect to run.
 *
 * Sample:
 *
 *     checkAngularModuleDependencies("app")
 *
 * Results are written to console.
