+  -------------------------------------------------------------------
+    Class to get HTTP GET-style variables from the document URL.
+    Usage:
+    1) declare a variable as GetVariables ex.
+         vars=new GetVariables();
+    2) call the variable's Init function ex.
+         vars.Init();
+    3) call IsVar to check whether the named variable is found ex.
+         vars.IsVar("username");
+       IsVar returns either true or false.
+    4) call GetVar to retrieve a variable.
+         alert(vars.GetVar("username"));
+       GetVar returns "" if the variable is not found.
+    
+    You can also iterate through the variables using
+    for(i=0;i<vars.VarCount();i++)
+    {
+     alert(vars.GetVarNN(i)+"="+vars.GetVarNV(i));
+    }
