Start to use __init__.py in main package folder

[eepeterson]

init.py is sort of the entry point for package import. This is where we can control how/what stuff gets imported from other areas of the package. If your feature is small enough, you can add from fusion_toolbox.mymodule import * it would also be good to put the version of the project there with __version__ = 0.1.0

Generally unless the feature is extensive and warrants it's own subpackage, modules can be placed directly within the package fusion-toolbox
