Function startTheComparisonProcess

startTheComparisonProcess(
    checker: LocalChecker,
    mainSolution: LocalSolution,
    targetSolution: LocalSolution,
    testsets: LocalTestset[],
): Promise<void>

Parameters
- checker: LocalChecker
  Checker configuration
- mainSolution: LocalSolution
  Main correct solution
- targetSolution: LocalSolution
  Solution to validate
- testsets: LocalTestset[]
  Array of testsets to check
Returns Promise<void>
Throws
If verdict validation fails

Throws
If main solution has unexpected errors
Example
```
// From fullVerification and testSolutionAgainstMainCorrect
await startTheComparisonProcess(
  config.checker,
  mainSolution,
  waSolution,
  config.testsets
);
```
