Implement updating the content of a snippet tag with the help from a method implementer. A snippet might invoke overriding a method though a completion and when a parent method is inserted it might contain javadoc. In this case it's impossible to recreate a snippet tag because the new text for the tag contains "/**" and "*/" that come from the parent method's javadoc. The implemented method implementer helps to strip a method's javadoc if it's present.
