BeanDefinitionParser implementation for the '<lang:groovy/>', '<lang:std/>' and '<lang:bsh/>' tags. Allows for objects written using dynamic languages to be easily exposed with the org.springframework.beans.factory.BeanFactory.

The script for each object can be specified either as a reference to the resource containing it (using the 'script-source' attribute) or inline in the XML configuration itself (using the 'inline-script' attribute.

By default, dynamic objects created with these tags are not refreshable. To enable refreshing, specify the refresh check delay for each object (in milliseconds) using the 'refresh-check-delay' attribute.
