+<ul><b>Generic sequence number:"</b> New generic sequence number class to 
+easily handle comparison, subtraction, etc. for sequence numbers.  
+To use it you need to supply two fundamental types as template parameters: 
+NUMERIC_TYPE and SIGNED_TYPE.  For instance, SequenceNumber<uint32_t, int32_t> 
+gives you a 32-bit sequence number, while SequenceNumber<uint16_t, int16_t> 
+is a 16-bit one.  For your convenience, these are typedef'ed as 
+SequenceNumber32 and SequenceNumber16, respectively.
