/*! \file ArMapInterface.h
* \brief Contains the set of interfaces that define the Aria maps.
* \date 06/27/08
* \author K. Cunningham
*
* The methods that define the Aria maps are grouped into a set of smaller
* interfaces which are contained in this file. These include:
*
* - ArMapScanInterface : Methods related to scan data (e.g. points and
* lines) generally obtained from a specific sensor (such as the SICK laser
* or Hokuyo URG).
*
* - ArMapObjectsInterface : Methods related to the objects in a map.
* These include user-defined objects such as goals, docks, and forbidden
* lines. They also include special "data" types of objects that may be
* automatically created during the scanning process.
*
* - ArMapInfoInterface : Methods related to the various info arguments
* stored in a map. Examples of info include the map object type
* definitions and the routes and macros.
*
* - ArMapSupplementInterface : Methods used to access supplemental data
* associated with the map. This currently consists only of the latitude /
* longitude of the origin, but may be extended in the future.
*
* The primary interface implemented by all Aria maps is also contained in
* this file:
*
* - ArMapInterface : All of the methods that are available for an Aria map.
* This interface extends all of the above interfaces and contains a
* few additional file-related methods.
*
* In general, when passing an Aria map (pointer) as a parameter to a method,
* it is preferable to pass ArMapInterface *. This will allow for extension
* and different implementations of the interface.

/**
* ArMapInterface defines the methods that are available on all Aria maps.
* These maps represent the operating space of a robot, and can be used for
* space searching, localizing, navigating etc. The types of data stored
* in a map include sensable obstacles (e.g. walls and furniture in a room)
* represented either as a collection of data points (similar to a raster
* or bit map, useful for high resolution sensors like a laser), or lines
* (a vector map, useful for low resolution sensors like the sonar),
* goals, and other points or regions of interest ("map objects").
*
* The methods in ArMapInterface can be broadly categorized as follows:
* - Scan Methods: These provide access the sensable obstacles that are
* represented as a collection of data points or lines. These are
* typically generated during the scanning process (i.e. the creation of
* the .2d file). If more than one sensor is used, then the data is
* organized on a per-sensor basis. The scan methods are grouped into
* the ArMapScanInterface.
* - Object Methods: These provide access to the "high-level" objects
* in the environment. Such objects include goals, docks, forbidden
* areas, and other user-defined points of interest. They may also
* include special data objects that are actually part of the operating
* environment and are generally added automatically and are not editable
* by the user. The object methods are grouped into the
* ArMapObjectsInterface.
* - Info Methods: A wide variety of supporting information is included
* in various "info" categories. This includes definitions for the
* types of map objects that can be stored in the map. It also includes
* various optional features such as macros and schedules. The info
* methods are grouped into the ArMapInfoInterface.
* - Extra Data Methods: These are essentially the "leftovers" -- i.e.
* methods that are related directly to map data but which do not
* fit into any of the above categories. They are defined in the
* ArMapSupplementInterface.
* - Callback Methods: Users of the Aria map may install callbacks onto
* the map in order to be notified when the map contents has changed.
* These methods are defined below.
* - File and I/O Methods: Methods to read and write map files are also
* included below. In addition, the MD5 checksum of the map contents
* may be calculated.
*
* TODO:
* - Possibly make the calculation of checksums optional?

* The Aria map provides an advanced feature that allows a parameter list
* to be defined for custom map object types. (Refer to the ArMap MapFileFormat
* for more information.)
*
* This convenience method provides access to the parameter values for a
* specified map object. It is basically a shortcut for searching and
* parsing the CairnInfo argument list. Unlike the CairnInfo arguments
* (which also include an introduction and map object name), the
* argument builder returned by this method only contains the parameter
* values. Also note that if the argument builder contains string
* parameters, then they may be surrounded by quotes.
*
* The returned pointer should not be stored, modified, or deleted.
*
* See setMapObjectParams for important information about changing the
* parameter values or the associated map object.
*
* This method is not thread-safe. (The call and use of the returned
* ArArgumentBuilder should be surrounded by calls to lock()/unlock().)
*
* @param mapObjectName the unique char * name of the map object whose
* parameters are to be retrieved
* @return ArArgumentBuilder * a pointer to the map object's parameter
* values;
