Fixed issue #52

I solved this two times, the first one was to add a CTOR into BindingInfo accepting a single "key" reference.

It was working, but because of concurrent errors in test, I though I had messed everything and came up with this second method.

The first one require no modification to EDRunner, JukitoRunner and Jukito module. I feel I should revert.

I'll open a second PR with this alternative method and tell me which one you guys prefers
