Output formalizes the access to a value of interest computed by the owning Component.
The value is then exposed and easily accessible for use by other components (e.g. to satisfy an Input). The purpose of an Output is to bind a value of interest to a component's member function (generator), and provide a generic interface to the value, its type and label so it can be easily identified. It also specifies the realization (computational) stage at which the value is valid, so that a caller can provide adequate error handling.
For example, a Body can have its position transformation with respect to
ground as an Output, which is only accessible when the model has been realized to the Position stage or beyond, in which case it depends on the Position stage. The validity of data flow can be checked prior to initiating a simulation.
An Output is intended to lightweight and adds no computational overhead if the output goes unused. When an Output's value is called upon, the overhead is a single redirect to the corresponding member function for the value.
An Output can either be a single-value Output or a list Output. A list Output is one that can have multiple Channels. The Channels are what get connected to Inputs.
