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.

Add an enclosing class for snippets in order not to make users define a class in a snippet code to eliminate syntax errors when the code consists of a set of instructions

JEP-413 says that by default a snippet tag's body is in JAVA language, so JavadocInjector injects JAVA into a snippet tag automatically. The injector relies on the lang attribute to inject a language, if the attribute is not present, then JAVA is used.
In order to make a user's live easier the injector doesn't make user guess the correct language name, instead if the injector didn't find a language by the value from the `lang` attribute it traverses throughout all the registered languages and looks for the one the name of which matches the specified ignoring case. That is the case for java: in our code base the language goes by the `JAVA` id, but users tend to write the language name in lowercase ("java") or with only the first letter in the capital case ("Java")
