 /**
 27  
  * Basic configuration classe. Stores the configuration data but does not
 28  
  * provide any load or save functions. If you want to load your Configuration
 29  
  * from a file use PropertiesConfiguration or XmlConfiguration.
 30  
  *
 31  
  * This class extends normal Java properties by adding the possibility
 32  
  * to use the same key many times concatenating the value strings
 33  
  * instead of overwriting them.
