Mutation testing with the mutant gem

Mutation Testing is awesome! And it is used to evaluate the quality of existing software tests by modifying the program's source code, based on well-defined mutation operators. Each 'mutated' version is called a mutant and a test which detects the mutation (fail) will kill the mutant. Mutants without failing tests are alive!
