ScriptingContainer (JRuby API)

MULTIPLE RUBY CONTEXTS ARE HARD. OHWAIT:

ScipritngContainer provides various methods and resources that are useful for embedding Ruby in Java. Using this class, users can run Ruby scripts from Java programs easily. Also, users can use methods defined or implemented by Ruby. ScriptingContainer allows users to set configuration parameters, which are per-container properties and per-evaluation attributes. For example, a local context scope, local variable behavior, load paths are per-container properties. Please see PropertyName and AttributeName for more details. The per-container properties should be given prior to the Ruby runtime is instantiated; otherwise, default values are applied to.
