Gittey config directory hierarchy

[jason-kerney]

I need the ability to chain gittey aliases to aliases in sub directories. Such that with the example setup shown below:

Root
  ˫ gittey-config.json
     ˪ alias: docs
  ˫ Sub-Directory A
     ˫ gittey-config.json
       ˪ alias: docs

I want to chain the root directory's gittey allias docs to call the sub directory's alias docs from the sub directory. However it is important that the active directory reverts back to the root directory.
