Refactor the input handling logic (#48)

* Add support for wrapper types

* Move `FilesWithExtensionIterator` to `core::common`

* Remove unneeded use of two `HashMap`s

* Make metadata structs more typed

* Impl new_from for wrapper types

* Implement the new input handling logic

* Fix edge-case in input handling

* Ignore macro doc comment tests

* Correct comment

* Fix edge-case in deployment order
