minor changes

more examples

changed and retracted change of location of code lemmas.

ignore repeated vars on lhs, cleanup

improvements for nbe

reformatting

subset_refl now included using the atp attribute

moved the "use" directive

fixed the bugs itroduced by the previous commit

made some small changes to generate nicer latex-output

split the files - Iteration.thy contains the big proof of the iteration combinator - Recursion.thy derives from Iteration the recursion combinator - lam_substs.thy contains the examples (size, substitution and parallel substitution)

Added in a signature.

fixed a problem where a permutation is not analysed when the term is of the form (pi o f) x1...xn This was the case because the head of this term is the constant "nominal.perm". Now an applicability predicate decides the right behaviour of the simproc

streamlined the proof

refined representation of codegen intermediate language

some small tunings

added fresh_fun_eqvt theorem to the theorem collection

added initialisation-code for finite_guess

made some small tunings in the decision-procedure (in the order how the "small" tactics are called)

Added setup for "atpset" (a rule set for ATPs).
