My goal is to use one Swift package to create multiple libraries.
I would like projects that depend on this package to be able import on the libs they want.
For example my Package would be call Foo, but it exports Bar and Baz.
External code can import the entire lib or pieces of it
import Foo // all the libs in the package Bar and Baz import Bar // just import Bar from Foo Swift Package
Follow up question, can you specify which source files can be associated with a target? Currently it is all the code in sources are part of the target.
