Provide a way to create the machine

Browse Source 
The BasicQueue returned obscures the TendermintImport struct. 
Accordingly, a Future scoped with access is returned upwards, which when 
awaited will create the machine. This makes creating the machine 
optional while maintaining scope boundaries.

Is sufficient to create a 1-node net which produces and finalizes 
blocks.
