Prepare infrastructure for tests

[SwinX]

Need to add following infrastructure items in order to start working with tests:

1. Add following modules to dev-dependencies: chai, lodash.
2. Remove modules from dev-dependencies: must
3. Add stub for resolve method. Stub needs to be implemented using single entry point style (i.e. need to have index.js as lib entry point)
4. Remove fake.test.js file.
5. Rename test folder to spec
6. Add folder named resolve to spec folder.
