2011-01-17 Christian Urban moved high level code from LamTest into the main libraries.
2011-01-17 Christian Urban eliminated tracing code; added flag so that equivariance is only proved for the function graph, not the relation
2011-01-15 Christian Urban subst also works now
2011-01-15 Christian Urban nominal_function works now completely for frees and depth; still a propbelm with subst; no unproved assumptions
2011-01-14 Christian Urban strengthened renaming lemmas
2011-01-13 Christian Urban added eqvt_lemmas for subset and psubset
2011-01-10 Christian Urban a few lemmas about freshness for at and at_base
2011-01-10 Christian Urban added a property about finite support in the presense of eqvt_at
2011-01-09 Christian Urban instantiated fundef_ex1_eqvt_at theorem with the indction hypothesis
2011-01-09 Christian Urban solved subgoals for depth and subst function
2011-01-09 Christian Urban added eqvt_at premises in function definition - however not proved at the moment
2011-01-07 Christian Urban added one further lemma about equivariance of THE_default
2011-01-07 Christian Urban equivariance of THE_default under the uniqueness assumption
2011-01-07 Christian Urban derived equivariance for the function graph and function relation
2011-01-06 Christian Urban a modified function package where, as a test, True has been injected into the compatibility condictions
