for Myghty components. It serves as a "home base" for configuration information and request
construction, and also assists the Request object in locating components. The Interpreter
maintains a pool of component objects and handles, at a high level, their compilation
and filesystem representation.iÿÿÿÿ( t *Nt Interpreterc B sM e Z d Z d d d d d d e e e i i e i ƒ e

be any subclass of ComponentSource. If the component was already loaded and exists
within this Interpreter's code cache, returns the existing Component. If the Component
has been modified at its source, it will re-load or re-compile the Component as needed.
If this Component has not been loaded, it will import or compile the Component as needed.
This operation is also synchronized against other threads. On systems that support
file-locking it is synchronized against other processes as well.
