config-check

Copperbox revision 3070.

Minor style changes to improve writing checkers - the path operator[*] has been given a very low precedence which lets it play well with the Applicative combinators.

Added an mget combinator to make projections (gets) returning Maybe values deterministic - code can act as if the projection is successful, if it has failed it is transparently caught by the underlying Either monad.


[*] The path operator has changed its ASCII name. The current name may not be final - naming ASCII operators is a bane of programming in Haskell.
