mutator: Mutation Testing

Performs mutation testing for 'R' packages to assess the effectiveness of a test suite. It mutates source files, runs package tests against each mutant, and reports which mutants were killed, survived, or timed out. Parallel execution is supported for larger code bases. The optional 'imputesrcref' package, available from <https://github.com/PRL-PRG/imputesrcref>, improves source locations when installed.
