+If I were just using GCC, which comes with the CGI "STL" implementation, I would
+use hash_map (which isn't part of the ANSI/ISO standard C++ STL, but hey it's nice).
+Using a plain map is just too slow for training on large files (or it is with certain
+STL implementations). I'm sure training could be made much faster still, but that's
+another matter...
+
+While I could (and probably should) get a hash_map for VC++ from
+http://www.stlport.org I thought it would be nicer if people didn't have
+to download extra stuff and then have to get it working alongside the STL
+with VC++, especially for just one small part of Dasher.
+
+The result is this:
+***************************************************
+very much thrown together to get Dasher out ASAP.
+***************************************************
+It is deliberately not like an STL container.
+However, as it has a tiny interface, it should still be easy to replace.
+Sorry if this seems really unprofressional.
+
+Replacing it might be a good idea. On the other hand it could be customised
+to the needs of the alphabet, so that it works faster. For example,
+currently if I have a string "asdf", it might be that "a" is checked
+then "as" is checked then "asd" is checked. I shouldn't need to keep
+rehashing the leading characters. I plan to fix that here. Doing so with
+a standard hash_map would be hard.
+
+
+Usage:
+alphabet_map MyMap(NumberOfEntriesWeExpect); // Can omit NumberOfEntriesWeExpect
+MyMap.add("asdf", 15);
+symbol i = MyMap.get("asdf") // i=15
+symbol j = MyMap.get("fdsa") // j=0
+
+You can't remove items once they are added as Dasher has no need for that.

+/* Explanation of NoClones {{{
+
+C++ defines default copy constructors and assignment operators, which clone
+every member of a class. Stroustrup describes this behaviour as the result of
+"historical accident". For many non-trivial classes, especially those
+containing pointers, this default behaviour is too naive. In fact it often leads
+to heap corruption.
+
+Sometimes it does not make any sense to copy an instance of a class. For
+example if it contains a unique file handle, or other lock on a system resource.
+Sometimes it is too much effort to write reliable replacement copy operations[1].
+In either case a private copy constructor and a private assignment operator
+prevent accidental copying. [2]
+
+Deriving a class from this class has the same preventative effect. It is also a
+bit neater and means that all the above explanation is centralised here.
+
+IAM 09/2002
+
+[1] An example of how it is very easy to make mistakes:
+http://www.mistybeach.com/articles/WhyIDontLikeCPlusPlusForLargeProjects.html
+If we don't need a copy feature it really isn't worth the hassle.
