CREATE SOURCE                   *deoplete-create-source*

To create source, you should read default sources implementation in
rplugin/python3/deoplete/source/*.py.

The files are automatically loaded and deoplete creates new Source class
object.
Source class must extend Base class in ".base".

Note: The sources must be created by Python3 language.

Note: If you call Vim functions in your source, it is not asynchronous.
