MVI branch

[tunjid]

An experimental branch for MVI style state production.

It offers feature parity with the existing branch and tries to establish some core MVI state production concepts:

Idiomatically functional: All inputs are eventually reduced into the UI state No side effects: all changes to state must be modeled in the stream Restricted UI state visibility: The state production pipeline cannot read the UI state until is ready to make changes to it Well defined inputs: All information required to process an action must be present at the input of the action
