/**
 * @brief RFC Code Message Fingerprint
 *
 * This Class will implment the rfc fingerprint version 2.
 * It will mainly consist of a tree of single "checksum nodes", each one
 * standing for a different rfc code. In this way, one rfc numeric code may
 * have arbitrary multiple checksum messages. When creating the error value, it
 * will only check against the ones with the lowest difference in the tree. I
 * need to invent something like a minimum/maximum number of checksums for
 * this, since a fp with much different checksums will then have a bigger error
 * value than one with only a few... I don't know if this will affect the
 * accuracy somehow.  To the saving. We will always add 1000 to a fingerprint
 * value. Every value < 1000 will then indicate that the following numbers are
 * for a new rfc return code. This will hopefully give us some flexibility in
 * hand-maintaining the fingerprints.
