+  /* Validate project names. Use unique project names
+
+     All arguments accepted by this function are JQeury objects.
+
+     For example if the HTML element has "hint-error-project-name", then
+     it is passed to this function as $("#hint-error-project-name").
+
+     Arg1 - projectName : This is a string object. In the HTML, project name will be entered here.
+     Arg2 - hintEerror : This is a jquery object which will accept span which throws error for
+            duplicate project
+     Arg3 - ctrlGrpValidateProjectName : This object holds the div with class "control-group"
+     Arg4 - enableOrDisableBtn : This object will help the API to enable or disable the form.
+            For example in the new project the create project button will be hidden if the
+            duplicate project exist. Similarly in the projecttopbar the save button will be
+            disabled if the project name already exist.
+
+     Return - This function doesn't return anything. It sets/unsets the behavior of the elements.
