* WARNING: DEBUGGER needs to accurately reflect whether or not the Debugger component is (or will be) loaded.
* In the compiled case, we rely on the Closure Compiler to override DEBUGGER as appropriate. When it's *false*,
* nearly all of debugger.js will be conditionally removed by the compiler, reducing it to little more than a
* "type skeleton", which also solves some type-related warnings we would otherwise have if we tried to remove
* debugger.js from the compilation process altogether.
*
* However, when we're in "development mode" and running uncompiled code in debugger-less configurations,
* I would still like to skip loading debugger.js altogether. To do that, we must arrange for an additional file,
* nodebugger.js, to be loaded as early as possible, which must explicitly UPDATE the value of DEBUGGER to *false*.

* We still need some Debugger "stub" objects, so that attempts to reference Debugger constants won't trigger exceptions.
