+
+
+Dependencies
+======
+Only to Qt5
+
+
+How to Use?
+======
+1) Include the QtJson.pri file into your pro file
+2) Create your class inhering the JObject class
+3) Your class's default constructor shuold be marked with Q_INVOKABLE
+4) Add properties to your class using the macros --  
+  i) Use MetaPropertyPublicSet to declare properites of built-in types (QString, int and such, that is, all the types in QMetaType::Type enum)
+  ii) Use MetaPropertyPublicSet_Ptr to declare property of your other JObject base custom types.
+  iii) Use MetaPropertyPublicSet_Ptr_List to declare property of list type of your other JObject base custom types. You will see a append<PropertyName> method in the class to append an item in the list of that particular type.
+See the test project in test directory for a bit more details.
