This read-only map returns the logical 'and' of the values of the two given maps. Its Key type is inherited from M1 and its Value type is bool. M2::Key must be convertible to M1::Key.
If m1 is of type M1 and m2 is of M2, then for 
 am[x] will be equal to m1[x]&&m2[x].
The simplest way of using this map is through the andMap() function.
