// This class will create a .<name> directory in the users home directory or
// a directory for the users choice. It will then manage a set of key values
// that the programmer can search for. This allows programmers to save a users
// settings and then retrieve then at a latter time. It currently supports
// upto 1024 different settings.
// Two constructors are provided. They will dertermine what directory to look
// for the settings file and what the name of the file is. If the directory is
// not specified then a default directory of .<DEFAULT_DIR> will be created in
// the users home directory. A file will be created in this directory. The name
// will be the one specified by the caller. If none is specified then
// DEFAULT_FILE will be created.
// To retrieve and store strings into the file readSetting and writeSetting
// should be called.
