BlockTypeCollection
BlockTypeCollection.Enumerator

These C# classes implement a strongly-typed collection of 
Rabbit objects.

The public representation is an array of Rabbit, so the performance 
characteristics will be more like a vector than a list, to use STL terminology.

The implementation is optimized for value-types, as it goes to great length to 
avoid the overhead of boxing and unboxing.  But it should also work well for 
reference types.

Mad props to Nick Wienholt, Kit George, Joel Mueller, Ethan Smith, Chris Sells, 
and Patrice Lafond for assisting me, at various times and in various ways.

Especially to Kit George, for his generous contribution to the dotnet mailing 
list -- a code-generator for CollectionBase-derived classes:

This was the original inspiration for the fine code you are now enjoying.

I discovered C# and .NET 1.0 Beta 1 in late 2000 and loved them immediately.
I have been writing software professionally in C# ever since

In real life, I have spent 3 years travelling abroad,

I now live near idyllic Bournemouth in England.

I can work 'virtually' anywhere!
