The scripting environment contains scripts that provide an environment to a user provided script. The environment may contain additional libraries or imports.

The environment performs lazy initialization of scripts: the first time a script of a given script language is executed, the environment will use the {@link ScriptEnvResolver ScriptEnvResolvers}for resolving the environment scripts for that language. The scripts (if any) are then pre-compiled and cached for reuse.
