lift_definition and setup_lifting generate parametric transfer rules if parametricity theorems are provided

simplified basic termination proof

some simp rules for fset

avoid -Infinity which confuses JFreeChart histogram;

tuned proofs -- more structure, less warnings;

tuned signature -- prefer terminology of Scala and Axiom;

better message (type-unsoundnesses are becoming rare, usually the issue is elsewhere, e.g. in the TSTP proof parser)

avoid using Arith_Data.dest_sum in extended-nat simprocs (it treats 'x - y' as 'x + - y', which is not valid for enat)

netlimit is abbreviation for Lim

tuned proofs

changed has_derivative_intros into a named theorems collection

changed continuous_on_intros into a named theorems collection

changed continuous_intros into a named theorems collection

add tendsto_eq_intros: they add an additional rewriting step at the rhs of --->

major redesign: order instead of preorder, new definition of intervals as quotients

added lemma

extended numerals

removed unused Future.flat, while leaving its influence of Future.map (see bcd6b1aa4db5);

extended stream library a little more

extended stream library

generalized lemmas in Extended_Real_Limits

eventually nhds represented using sequentially

generalized compact_Times to topological_space

move lemma Inf to usage point

tuned proof of Edelstein fixed point theorem (use continuity of dist and attains_sup)

tuned proofs (used continuity of infdist, dist and continuous_attains_sup)

generalized continuous/compact_attains_inf/sup from real to linorder_topology
