+* The MbedJSONValue is memory hungry class as I think.
+* If your platform has enough SRAM, you can go for it.
+* The library itself works fine but user need to caution using it.
+* It's fine with this:
+*  MbedJSONValue &ele = demo["menu"]["popup"]["menuitem"][i];
+* It's big problem with this(without &):
+*  MbedJSONValue ele = demo["menu"]["popup"]["menuitem"][i];
