/**
* This interface represents a script compiler.
*
* The default (no-parameter) constructor is required to be available (public)
* for a compiler, since compilers are located and loaded dynamically by
* inferring the compiler class name from the language name, and then
* instantiating the compiler dynamically.  As a result, the constructor must
* be predictable, and the no-parameter constructor is the easiest to use.
*
* A side-effect of the default constructor is that the compiler has no state
* after it is created.  Therefore the compile method acts as both an
* initializer and a command to compile.  If the compiler has global state
* (uses fields to store its state) then the compile method must be
* synchronized in case the compilation process is multi-threaded.
*
* The compiler may be re-used (multiple calls to compile) or may be used only
* to compile a single script.
*
