Added a special charcount threatment to the 'append' csymbol (whose length
was estimated being 6 instead of 3). We should do the same for every csymbol
we provide special notation to.

Rearranged tactics in VariousTactics into new modules EqualityTactics, EliminationTactics,
IntroductionTactics and NegationTactics.
Added new tactics: Rewrite <-, Replace.
positive.xsl is now included in headercontent.xsl and no more required in
arith.xml and list.xml. This is necessary to overload the standard rendering
of some operators (e.g. notation for real numbers).
* New button "Select only constants" to choose the URIs to try during the
disambiguation phase. Usually the number of constants is small and among
them there is the right URI.
* New ElimIntrosSimpl replaces the old ElimSimplIntros.
* mQueryLevel2.get_constraints now gives back only the "must" constraints.
* the "refine constraints" interface has been improved. It can now handle
also constraints on Sorts and constants.
The fresh_name generator has been moved to ProofEngineHelpers.
intros_tac now directly uses it ==> no more ~mkname arguments.
The generator has been "improved" so that it does not generate any
more two equal names. The drawback is that every identifier is
augmented with a nonce.
Bug fixed: when iota-expanding fixpoints the context was sometimes augmented
with the new types, even if the expansion already de-lifted the function body.
The user interface for the completeSearchPattern query has been improved.
It is now "easy" to query for induction principles, for example.
Much work still to do.
1. depth constraints for Rels and Sorts are now optional
2. "can" constraints renamed to "only" constraints
3. several bug fixes:
* the order of arguments for Sub in the second phase of the query was wrong
* some identifiers in the generated query were unbound
Bug fixed: the lhs part of an explicit name substitution was not generated
as an m:ci, but as simple text ===> no m:mi and no hyperlink were generated.
* mQueryLevels interface clean-up
* gui improvement: the precision level of the SearchPattern query is now
chosen by the user. Previously it was guessed.
* fold_tac has now a new parameter, which is the reduction to ``undo''
* The Fold button is replaced with Fold_whd and Fold_reduce
* Minor interfaces modifications
First working version of the possibility to introduce new inductive type
definitions. Many checks have not been implemented yet and the interface
allows you to progress to further stages even if the input is incorrect.
Nevertheless, if the input is correct it will be accepted by the kernel,
saved to disk and notified to the getter.
put_inductive_definition implemented and exposed.
It is a very UNSAFE solution to the problem of computing inner-types of
non-debrujined mutual inductive types (whose constructors referes to
the not-yet-defined inductive type block): you can use this function to
add the block to the environment; then you compute the inner-types; and
finally you save the object and register it to the getter.
typecheck_mutual_inductive_defs exposed.
It is used to type-check and inductive definition which has no URI associated
to it (i.e. it is not managed by the getter; e.g. when it is not saved yet
since we do not know if it is well-typed).

Added new tactics: Exists, Split, Assumption, Absurd, Generalize (doesn't work)
Moved ElimType from ring.ml to variousTactics.ml
Moved Contradiction from fourierR.ml to variousTactics.ml
First implementation of the new generalized SearchPattern on the whole
type (not only the conclusion). Despite the file name, no levels have
been implemented so far.
Brand new implementation based on functors taking a strategy in input.
Several different strategies have been implemented. Unfortunately many
of them are incomparable and there are critical examples where only some
of them terminate in reasonable time.
Removing the functor/module stuff does not bring any sensible performance
improvement even for simple strategies (where most of the functions are
just identity fuctions that can be inlined when not crossing functor
boundaries).

- now esempi/fourier/ is he dir for all fourier extras
- fourier.cic some tests
- fourier_benchmarks.cic some test computionally interesting
- fourier_make_benchmarks.ml a simple tool to generate big systems of
inequations
lazily ==> call_by_name (since it is really a call_by_name!)
The default is now false (i.e. call_by_value strategy) to make an example
of Fourier application type-check in 8s instead of 1h40m!!!
We also tried a call_by_need strategy (not committed).
The results obtained are so far equivalent to the call_by_value strategy
(that is why we did not commit the code).
* The new query language (now broken) works only on the new DB
helm_mowgli_new_schema.
* InConclusion, InHypothesis and so on are now inserted in the DB with their
namespace.
- catch processing exception which are now reported embedded in html responses
- catch parameter exception which are now reported as bad request responses
- changed default port from 48085 to 58085
- disabled http debugging
WARNING!!!
From now on the V7_3_new_exportation branches of ocaml/mathql and
ocaml/mathql_interpreter are DEPRECATED!!! You must switch back to
the main branch.
