[nicojs]

Integrate the new TestRunner and TestFramework apis in Stryker. Make sure to support the options we already had, maybe rename them.

Work on this has started in the branch: https://github.com/infosupport/stryker/tree/next-runner

The following command:

node dist/src/Stryker.js -s test/sampleProject/src/Add.js,test/sampleProject/src/Circle.js -t test/sampleProject/test/AddSpec.js,test/sampleProject/test/CircleSpec.js

Should print the following output to the console:

INFO: Running initial test run
INFO: Initial test run succeeded
INFO: 11 Mutants generated
INFO: Waiting for all code coverage reports to finish
INFO: All code coverage reports have been collected
INFO: Testing mutants:

Mutation: Math
-     return 2 * Math.PI * radius;
+     return 2 * Math.PI / radius;


Tests ran:
    C:\Users\simonl\Documents\workspace\stryker\test\sampleProject\test\CircleSpec.js


9 mutants tested.
2 mutants untested.
0 mutants timed out.
8 mutants killed.
Mutation score based on code coverage: 88.89%
Mutation score based on codebase: 72.73%

The messages about code coverage may be omitted due to the new coverage system. The 'tests ran' should now show the names of the specs which have been ran.
