This patch tidies up SimpleChain:
This patch tidies up SimpleChain:

1. Adds a description to the prologue.
2. Strips out the erroneous and now redundant thread-safety logic.
3. Removes the extraneous options hashtable field which is simply inherited from BasicHandler.
4. Initialises the 'handlers' Vector (since a permanently empty SimpleChain is a rarity).
5. Tightens up the scope of the visitor strategy objects making them private and final.
6. Fixes the trace logging of generateWSDL.
