A Builder for RuleSets. Create a RuleSet by calling the ruleset method, passing in a Closure defining the contents of the RuleSet. The Closure can contain any combination of the following (as well as arbitrary Groovy code):

• ruleset - to load a RuleSet file. The path specifies either a Groovy file or an XML file.
• rule - to load a single Rule (specify either the rule name or rule class)
• description - description of the RuleSet (optional)
