/**
 * @author Roman.Chernyatchik
 *
 * Group of linked params. Sometime it's much more convenient to split cmdline in logical groups.
 * In this case it will be easier to patch such grouped argements using custom extentions
 *
 * E.g.: we want to add Coverage support to all existing Ruby run configurations(ruby applications,
 * different kinds of ruby tests, rails configuration, etc). Coverage support require to reorder args
 * in cmdline, add rcov runner script, etc. Without groups it would be harder to parse abstract list of arguments
