/// Stores configuration information which may be read to and from files or other sources
/**
* The configuration is a set of parameters (or config arguments), organized into
* sections. Parameters contain a key or name (a short string), a value
* (which may be one of several types), a priority (important, normal, or trivial
* to most users), a longer description, and a display hint which suggests
* what kind of UI control might be most appropriate for the parameter.
* After adding a parameter to the configuration, its value may be changed
* when the configuration is loaded or reloaded from a file.
* Various program modules may register callbacks to be notified
* when a shared global configuration (such as the static ArConfig object kept
* by the Aria class) is loaded or otherwise changed.
*
* Classes dealing with more specialized kinds of config files
* inherit from this one.
*
* Important methods in this class are: addParam(), addProcessFileCB(),
* remProcessFileCB(), parseFile(), writeFile().
*
* Usually, configuration data are read from and written to a file using
* parseFile() and writeFile(), or are set
* by a remote client via ArNetworking. It is also possible to import
* configuration settings from an ArArgumentParser (which, for example, may
* contain a program's command line arguments) using useArgumentParser().
*
* @warning ArConfig does not escape any special characters when writing or
* loading to/from a file. Therefore in general parameter names, values, section
* names, and comments must not contain characters which have special meaning
* in a config file, such as '#', ';', tab or newline. (see also ArFileParser) Parameter names may
* have spaces, though by convention they generally do not.
