ENH: Find importable lib name. Find test imports
ENH: Find importable lib name. Find test imports

Add two functions.
- find_lib_name() will find the importable name of the library from the
  iterable of tuples that `iterate_over_library` returns. e.g., this
  function will return 'skxray' for the 'scikit-xray' library.
- find_test_imports() will turn the full module path from the return
  value of `iterate_over_library()` into a list of importable modules.
  e.g., turn '/home/edill/dev/python/scikit-xray/skxray/fluorescence.py'
  into 'skxray.fluorescence'. All of these importables are then put into
  the jinja template under 'test.imports'
