Detailed Description
class MayaFlux::Nexus::Perception< T >
A value of any type, read from the world through the perception context and handed to its targets.
T is whatever is sensed: a scalar from a node or buffer, a vector, a struct of readings, a Tendency, a DataVariant. The source reads it, using the context when it needs position or neighbours. A target is any callable taking const T& and decides where it lands, such as a cell the perception function reads. On each invoke the source runs once and every target gets the value, in the order they were added.
How many targets a Perception may have is decided by its owner: a Sensor keeps one, an Agent keeps as many as are added.
