description {
* @brief Access and update geometric features in a map. EXPERIMENTAL
Vectormap is an interface which provides access to geometric features in a map.
A vectormap contains a set of layers, each of which can hold a set of features.
This interface attempts to adhere to the OGC standard, an open standard for
representing
maps.
///TODO: Add more documentation describing OGC standard.
For more information about OGC see http://opengeospatial.org/
For more information about GEOS see
