Create framework for making complex computations more flexible

[lounres]

Make a framework that will provide out of the box such features:

1. Pause and resume computation serialising interim computation state
   Framework should be able to pause and resume end user's computation regardless of whether program will be stopped or not. Paused computation must be able to be resumed without (or with minimal) change of program source code. Interim computation state must be able to be serialised in a file. The file may (and apparently will) be used to serialise and deserialise the computational state. The serialisation may be delegated to end user. But it will awesome to come up with API to minimise user work. Also interim partial output data must be able to be serialised and returned.

2. Compute parallelly
   The framework must provide API for parallelising end user's computation.

3. UI
   The framework must provide ability to plug in CLI, web UI or any other UI. UI must contain elements for:

   1. stopping and pausing,
   2. progress bar and/or interim output data,
   3. (?) other components derived from interim results.

   The default web UI backend must just serve interim data. The default web UI frontend must be very simple. Web UI must be able to be changed (with inheritance or whatever) by end user including frontend replacement.

Possible feature: Develop a daemon like in Gradle or Kotlin compiler for the purpose of controlling the computations.
