Usage example

First real usage scenario was appeared during testing project with different major linux versions built on Ubuntu 16.04 machine.
Kernels 3.9, 3.11, 3.13, 3.15, 3.16, 3.17, 3.19 doesn't boot in qemu, but LTS kernels does boot successfully.
It's obvious that there is fix for boot issue somewhere.
bisectDemo added to project to demonstrate finding commit that makes project working again. Here is the tool's output:
