A Read/Write Property Map can be used to read property values via
the get() function and can be used to write property values
via the put() function.

Notation
| PMap |
A type that is a model of Read/Write Property Map. |
Associated Types
| Property Map Category
| boost::property_traits<PMap>::category |
The category of the property map must be a type convertible to
read_write_property_map_tag.
