Any dependencies from the zpl library will be exposed manually with using declarations into global scope.
They will be removed when the library is feature complete for version 1 (zero dependencies milestone).
*Right now the upfront constructors are working to some extent based on testing*
***The editor and scanner will NOT be implemented by version 1. They require alot code and the focus for version 1 is to have a robust constructor API and builder, witch a wide suite of usage examples in the tests for the project.***
