Class Reaction

A derivation is everything that can be derived from the state (all the atoms) in a pure manner. See https://medium.com/@mweststrate/becoming-fully-reactive-an-in-depth-explanation-of-mobservable-55995262a254#.xvbh6qd74

warn if the derivation has no dependencies after creation/update

runId

runId: number

Id of the current run of a derivation. Each time the derivation is tracked this number is increased by one. This number is globally unique
