broken with yo v1.5.0

[markfink]

I came here for a simple generator sample. When I install Yoga using yo version 1.5.0 I get the following:

? 'Allo Mark! What would you like to do? Yoga

Make sure you are in the directory you want to scaffold into.
This generator can also be run with: yo yoga

No yoga file found. Proceeding with simple copy.
