Description

Constrained model synthesis prototype. It tries to generate UtAssembleModel that creates an object using it's public API for each argument of the method under test.

Type of Change

New feature (non-breaking change which adds functionality)

How Has This Been Tested?

Automated Testing

Feature was tested on open-source projects: exp4j, guava, fastjson, etc.

AlsoSynthesisExamplesTest was added.

Manual Scenario

Example classorg.utbot.examples.synthesis.SynthesisExamples was added to theutbot-sample module. Running UtBot on the methods from that class withUtSettings.enableSynthesis set totrue should show several scenarios of how constrained model synthesis allows to generate test cases that use public API of the objects

Currently onlystateBefore is generated using constrained model synthesis.StateAfter is generated from concrete execution. In the future it is possible to add constrained model synthesis forstateAfter also, but it will at least double UtBot working time.

I will take a superficial review this week. You also ought to rebase on master.
