Option to allow multiple reporters and outputs #255
Description
It'd be nice to supply a list of reporters in the options in case I want multiple output or output formats. For example, I'd like to be able to send results to the console as well as to a file. I know it's possible to write a custom reporter, but in my case, I want to use the default for console and checkstyle to a file. So it doesn't make sense to basically combine and rewrite those two reporters into one when I could theoretically just pass that info in my options. In other situations, I may use the same style of default or checkstyle but still want to send it to both the console and a file.
