Introducing Stability and Structural Sharing to Microstates (#113)

* [WIP] build a tree that we know is good from the ground up.

* Merged eslint config

* Added basic composed state test

* Added memoize descriptor

* Show pretty error without crashing on failed build

* Rename memoize to stable

* construct a Transitions class and collapse it.

* Gathering transitions

* Removed unnecessary initialization

* Removed Transitions from stable

* Value is stable

* Added the functor and prune/graft

* Added comments

* It's now possible to lens the tree

* WIP shape-shift enabled tree-lenses (kinda)

* convert while loop to foldr

* Added basic transitions tests

* Removed unnecessary code

* Invoke is called through the tree

* Implement `Monad` instance for `Tree`

* Invoking method in transition tests

* only call append in transitions if there are children

* Moved transitions back to Tree

* Revert "Moved transitions back to Tree"

This reverts commit 8e9667da3.

* Made the tree tests pass

* Moved building microstate type into Microstate.for

* Added mapping middleware

* Added Tree Semigroup

* Externalized and cached Type constructor

* Make sure that middleware is carried over into the next state

* Updated flatmap to preserve root

* Basic initialization is working

* Added reinitialization test
