+* \class CiphersSingleton
+* \brief Singleton-Class to assign a short descriptive string and a number for all Ciphers.
+*
+* This Class, basically, provides an Array containing QStrings, each of which is used as
+* description for an available cipher.
+* The index of each QString is also used to describe the cipher.
+* This is needed since sometimes ciphers need to be referred to by strings, and other times
+* by integers.
