  Change the macros to meet boost guidelines.
  
  I should really have done this before the review. At least it'll give them
  something to say.

  Explicity use the classic locale in the case insensitive example. I could make
  the locale a member, but that would make the example longer. Also, this would be
  a good place to put a note about the need for constant function objects.

  later.

Merge: When allocators aren't equal use a slow swap.

  Rewrite much of the 'controlling the number of buckets' section.
  
  I'm trying to make it clearer. It's a bit tricky as the standard doesn't guarantee much.
  Instead of diving straight into the details I have tried to give the reader a rough
  idea of what 'rehash' does and what the load factor is. This is hopefully enough to
  understand the more detailled discussion of how you can control the number of buckets.
  Then finally I discuss iterator invalidation.

[SVN r42403]
I missed an explicit conversion when accessing a bucket.

[SVN r42406]
Follow boost naming conventions.

[SVN r42407]
Make it clear that pointers and references to elements are never invalidated.


[SVN r42517]
Add a little bit of text about hash and equality functions to the intro, and add links to Boost.Hash.


[SVN r42518]
Some small tweaks to the hash function documentation.

[SVN r42519]
Minor tweak.

[SVN r42521]
No need to list all the types that std::hash and boost::hash support (the list will get out of date quickly). And try to make a little clearer that you will need to extend boost::hash or use a custom hash function (which was suggested in the review).

[SVN r42522]
Link to the hash function and equality predicates section from the data section.

[SVN r42523]
Minor tweak.

[SVN r42524]
Add note about intent to implementation operator== and operator!=.

[SVN r42525]
Add links to all the libraries that use Boost.Hash
