The Pure Data patch format
Starting out with the Pd data format as approaching some platonic
ideal, let's move towards finding a functional representation of that
platonic ideal. Let's stick to the format of the abstraction as what
it's all about (dac~ and adc~ are top level special cases of outlet~
An abstraction is:
* A set of sub-processors that define the available inputs and
* A set of connections that constrain the available inputs.
* Input abstraction: promote some open input nodes to the next
level / set other open input nodes to default. (Bind all inputs
as either abstraction inputs or constant inputs.)
* Output abstraction: promote some output nodes to the next leve /
ignore other output nodes.
Important observation: inputs and outputs are not symmetric. Each
input (variable) can be bound/assigned-to only once, but can be used
