-## @brief Decorator to have methods with the same name callable from Class or from Instance
-#
-# Usage example :
-# @code{.py}
-#   class A(object):
-#       @classinstancemethod
-#       def foo(self, a, b):
-#           print("foo() instance call", a ,b)
-#       
-#       @foo.classmethod
-#       def foo(self):
-#           print("foo() class call")
-#
-#       @classinstancemethod
-#       def bar(obj):
-#           if obj == A:
-#               print("bar() class call")
-#           else:
-#               print("bar() instance call")
-#
-# a=A()
-# A.foo() #foo() class call
-# a.foo(1,2) #foo() instance call 1 2
-# A.bar() #bar() class call
-# a.bar() #bar() instance call
