/*
This is the OpenMCT common webpack file. It is imported by the other three webpack configurations:
 - webpack.prod.js - the production configuration for OpenMCT (default)
 - webpack.dev.js - the development configuration for OpenMCT
 - webpack.coverage.js - imports webpack.dev.js and adds code coverage
There are separate npm scripts to use these configurations, though simply running `npm install`
will use the default production configuration.
