As Jeremy said earlier, the get() and put() functions can go anywhere they can
be reached by argument-dependent lookup when called as
get(property_map,key_value) or put(property_map,key_value,new_value).

The parameters are as I just showed --- i.e. the description is in terms of
valid call expressions, not in terms of actual function signatures.

To meet the concept described in Jeremy's docs, a property map must define the
necessary property_traits for its chosen category, and it must support get()
and/or put() and maybe operator[] as necessary for its chosen category.

As Jan Langer pointed out, there are specific pages for each of the property
map categories. If you missed these you will have difficulty piecing
everything together.
