Hi,I am not sure whether this is what you want:
1、initialize the global object user defined, for example , the object name is "Cloud".
   You can find examples in function: JSGlobalObject::reset(JSValue prototype),
   Create "Cloud" object just like "Date" or "Array".

2、Create these four files:
   CloudConsructor.cpp, CloudConstructor.h, CloudPrototype.cpp, CloudPrototype.h.

3、generate the hash table for "Cloud",just run:
   perl CloudPrototype.cpp >CloudPrototype.lut.h,  
  the rule is defined in CloudPrototype.cpp as follows:
// ------------------------------ CloudPrototype ----------------------------

const ClassInfo CloudPrototype::info = {"Cloud", 0, 0, ExecState::cloudTable};

/* Source for ArrayPrototype.lut.h
@begin cloudTable 16
  toString       cloudProtoFuncToString       DontEnum|Function 0
  toLocaleString cloudProtoFuncToLocaleString DontEnum|Function 0
  concat         cloudProtoFuncConcat         DontEnum|Function 1
  join           cloudProtoFuncJoin           DontEnum|Function 1
  pop            cloudProtoFuncPop            DontEnum|Function 0
  push           cloudProtoFuncPush           DontEnum|Function 1
  reverse        cloudProtoFuncReverse        DontEnum|Function 0
  shift          cloudProtoFuncShift          DontEnum|Function 0
  slice          cloudProtoFuncSlice          DontEnum|Function 2
  sort           cloudProtoFuncSort           DontEnum|Function 1
  splice         cloudProtoFuncSplice         DontEnum|Function 2
  unshift        cloudProtoFuncUnShift        DontEnum|Function 1
  every          cloudProtoFuncEvery          DontEnum|Function 1
  forEach        cloudProtoFuncForEach        DontEnum|Function 1
  some           cloudProtoFuncSome           DontEnum|Function 1
  indexOf        cloudProtoFuncIndexOf        DontEnum|Function 1
  lastIndexOf    cloudProtoFuncLastIndexOf    DontEnum|Function 1
  filter         cloudProtoFuncFilter         DontEnum|Function 1
  reduce         cloudProtoFuncReduce         DontEnum|Function 1
  reduceRight    cloudProtoFuncReduceRight    DontEnum|Function 1
  map            cloudProtoFuncMap            DontEnum|Function 1
how to use CloudPrototype.lut.h please check the "Date" or "Array" implementation.

4、 compile your added files and test your new object "Cloud".

If there is any mistake or missed detail please let me know , thanks!
