hypercubish algorithm skeleton
refactor: move classes into separate files
fix dependencies
implement #add_note_and_connect
add a more complex example test
rework based on remarks
coordinate based hypercubish generation
successfully generate 1024 node hypercubish

- method: coordinate based
- speed: incredifast
- awesomeness: infinity+1
experiments
set default connection strategy to coordinates
implement #remove_node
