restructure build environments?

In order to technically enforce the the inter-package dependencies as defined by the software architecture, one could manually specify the dependencies.

In order to achieve this:

1. Set LDF mode to off. This way dependencies will not automatically be resolved.
2. In each library/package specify the allowed dependencies. This may be achieved using library.json file. Although I am not sure if this works for local libraries as well.

Although related it is independent from #83.

Actually, if dependencies are defined within the libraries/packages, those could interfere with the dependency structure used for testing.
