Graph-Reducer

Something like lodash.merge() (a recursive version of Object.assign()) that specially designed for graph-stater.

It additionally supports functions (in payload(s) argument(s)) to make it possible to transform properties based on their previous states/values.

It also deeply compares the source state (source object) with the primary result (newState), during its original process and returns an additional value (noTransform) that shows the result of this comparison.
