acd57d74de Changed the A.Structured type to be parameterised 
This patch is actually an amalgam of multiple (already large) patches.  Those patches conflicted (parameterised Structured vs. changes to usage checking and FlowGraph) and encountered a nasty bug in darcs 1 involving exponential time (see http://wiki.darcs.net/DarcsWiki/ConflictsFAQ for more details).  Reasoning that half an hour (of 100% CPU use) was too long to apply patches, I opted to re-record the parameterised Structured changes as this new large patch.  Here are the commit messages originally used for the patches (which, as mentioned, were already large patches):

A gigantic patch switching all the non-test modules over to using parameterised A.Structured
Changed the FlowGraph module again to handle any sort of Structured you want to pass to it (mainly for testing)
A further gigantic patch changing all the tests to work with the new parameterised Structured
Fixed a nasty bug involving functions being named incorrectly inside transformInputCase
Added a hand-written instance of Data for Structured that allows us to use ext1M properly
Fixed a few warnings in the code

9cd2da3b0e A large change to alter RainUsageCheck to use the code in UsageCheck 
Previously there was near-duplicate code in UsageCheck adapted from RainUsageCheck.  This patch removed the duplicate code on the RainUsageCheck side, and resulting in changing the rest of the module (and its corresponding test module) to use the new UsageCheck version of the code.  The net effect is to almost completely unify the passes in RainUsageCheck (which aren't really Rain-specific anyway), UsageCheck and ArrayUsageCheck.
