-/**
- * TypedCode organizes implementation code based on the Type and Version of code it works with so that it can
- * be located quickly at runtime based on the "Accept" HTTP Header.
- *
- * FYI: For those in the future wondering why I would create a specialized set of "Pair" for the data content:
- * 1) TypeCode is used in Route, and this code is used for every transaction... it needs to be blazingly fast
- * 2) The actual number of objects accessed is quite small and built at startup. Arrays are best
- * 3) I needed a small, well defined tree where each level is a different Type. Using a "Pair" Generic definitions,
- * I created type-safety at each level, which you can't get from a TreeSet, etc.
- * 4) Chaining through the Network is simply object dereferencing, which is as fast as Java can go.
- * 5) The drawback is that in your code is that all the variables are named "x" and "y", which can be a bit hard to
- * read both in code, and in the debugger. However, TypeSafety allows your IDE (Eclipse) to help you make the
- * choices. Also, make sure you have a good "toString()" method on each object so you can see what's happening
- * in the IDE Debugger.
- *
- * Empirically, this method of obtaining routes proved to be much faster than the HashSet implementations available in otherwise
- * competent Open Source.
