public class BaseLib extends TwoArgFunction implements ResourceFinder
LibFunction which implements the lua basic library functions.
This contains all library functions listed as "basic functions" in the lua documentation for JME.
The functions dofile and loadfile use the
Globals.finder instance to find resource files.
Since JME has no file system by default, BaseLib implements
ResourceFinder using Class.getResource(String),
which is the closest equivalent on JME.
The default loader chain in PackageLib will use these as well.
To use basic library functions that include a ResourceFinder based on
directory lookup, use JseBaseLib instead.
Typically, this library is included as part of a call to either
JsePlatform.standardGlobals() or
Globals globals = JsePlatform.standardGlobals();
globals.get("print").call(LuaValue.valueOf("hello, world"));
For special cases where the smallest possible footprint is desired,
a minimal set of libraries could be loaded
directly via LuaValue.load(LuaValue) using code such as:
Globals globals = new Globals();
globals.load(new JseBaseLib());
globals.get("print").call(LuaValue.valueOf("hello, world"));
Doing so will ensure the library is properly initialized
and loaded into the globals table.
This is a direct port of the corresponding library in C.

Perform one-time initialization on the library by adding base functions
to the supplied environment, and returning it as the return value.
