angreal init Behavior

When you call angreal init <template> we use the following decision tree to determining where we look for templates for download.

This should allow for : - people to re-use templates after clone more easily by using something like, angreal init https://github.com/user/template and later with angreal init user/template.

• angreal to provide supported templates at https://github.com/angreal/template name that are accessible through both angreal init angreal/template or angreal init template

• local development of temlpates via angreal init path/to/template where the template can exist in ${HOME}/.angrealrc/path/to/template or just path/to/template

Functionally this means if you run angreal init python at least once the following commands would be synonymous : - angreal init python - angreal init angreal/python - angreal init ${HOME}/.angrealrc/python
