/**
* This class creates plugin instances from a String.
*
* The String is of the form name[:output] where name is either a fully qualified class name or one of the built-in short names.
* output is optional for some plugin (and mandatory for some) and must refer to a path on the file system.
*
* The plugin class must have a constructor that is either empty or takes a single argument of one of the following types:
*
*
{@link Appendable}
*
{@link File}
*
{@link URL}
*
{@link URI}
*
* Plugins must implement one of the following interfaces:
*
*
{@link gherkin.formatter.Formatter}
*
{@link gherkin.formatter.Reporter}
*
{@link cucumber.api.StepDefinitionReporter}
*
