## Detailed Description

A list of (daughterboard slot name, subdevice name) pairs:

A subdevice specification represents a list of subdevices on a motherboard. The subdevices specified may span across multiple daughterboards; Hence the need for a subdevice specification over a simple list of strings. Typically, the user will pass a RX or TX subdevice specification into the API, and the implementation will infer the channel configuration from the specification.

The subdevice specification can be represented as a markup-string. The markup-string is a whitespace separated list of dboard:subdev pairs. The first pair represents the subdevice for channel zero, the second pair represents the subdevice for channel one, and so on.

## Constructor & Destructor Documentation
