 *  \brief Contains the set of component classes used to implement Aria maps.
 *  \date 06/27/08
 *  \author K. Cunningham
 * 
 * The ArMap class (defined in ArMap.h) is composed of several smaller 
 * classes that are defined in this header file.  These include:
 * 
 *  - ArMapScan: An implementation of the ArMapScanInterface.  This 
 *    contains all of the data related to the sensed obstacles (i.e.
 *    data points and lines).  An instance of this class is created 
 *    for each scan type that is defined in the map.
 *
 *  - ArMapObjects: An implementation of the ArMapObjectsInterface.
 *    This stores all of the map objects for the Aria map.
 *
 *  - ArMapInfo: An implementation of the ArMapInfoInterface.  This
 *    contains all of the info (ArArgumentBuilder) tags defined for 
 *    the map, including MapInfo, TaskInfo, and RouteInfo.
 *
 *  - ArMapSupplement: An implementation of the ArMapSupplementInterface.
 *    This is a repository for all of the extra data that does not fit
 *    into any of the above categories.
 * 
 *  - ArMapSimple:  The RealSubject of the ArMap Proxy.  This implements
 *    the ArMapInterface and is an aggregate of all of the above map
 *    components.
 * 
 * The following "diagram" illustrates the basic hierarchy:

/// The map data related to the sensable obstacles in the environment.
/**
 * ArMapScan encapsulates the data for a particular sensor that is generated 
 * during the scanning process (i.e. during the creation of a .2d file).  
 * The class's primary attributes are the points and line segments that 
 * were detected during the scan.  It contains methods to get and set these 
 * coordinates, and to read and write the data from and to a file.
 * <p>
 * The <code>scanType</code> parameters identify the sensor used for scanning. 
 * The parameter is used in the constructor, but it is generally disregarded
 * in the other methods.  (The method signatures are defined in 
 * ArMapScanInterface, which is also implemented by ArMap.  The map provides
 * access to the scan data for all of the sensors -- and therefore uses the 
 * <code>scanType</code> parameters.  This interface was chosen in order
 * to maintain backwards compatibility with the original map.)
 * <p>
 * If the scanType is specified, then it is used as a prefix to the DATA and
 * LINES tags that are contained in the map file.
