/**
 * An Entity is a command that injects a context with a unique ID. State
 * is not preserved, but rather just provided. The current and previous states
 * are captured and provided to the scope block function given to the intance
 * entity function. The previous state is exposed as a property on the curren
 * state object. Basically, this class just constructs a command function
 * that accepts some input, injects a regl context, and passes it to an optional
 * block function. The context just defines an `entityID` property. Most
 * classes inherit from Component, which inherits Entity.
