Detailed Description

A measurement: an observed value with its model and the call's inputs, and the method a Kalman update pushes the state through, as observe() makes it; what update() and every filter's update() take (decisions.md [templated-measurements]).

A filter that weights points needs no method, and a Kalman update refuses a measurement without one at compile time.
