(!!! = may break code that uses previous versions)

version 0.5, November 15, 2022

Reworking the library build system, now only relying on dune. The Makefile is now clearer and simpler to use.
(!!!) Logs are handled by the logs library and debug is activated by this library.
(!!!) The Rat2 module now abstract bounds as strict upper, strict lower or soft bounds instead of pairs of rationals.

version 0.4, August 22, 2017

(!!!) Now, asserting bounds returns whether these bounds are trivially implied by those that are already known
add a field nb_pivots in the environment to count the number of pivots that have been made so far.

add support for linear optimization (!!!). An minimal example is given in tests/standalone_minimal_maximization.ml
some bugfixes when assuming inconsistent bounds
improve build and testing

A functor called Basic provides three modules:
- Core: provides some basic functions, and a function empty to create an empty environment
- Assert: exports two functions var and polys to assert bounds on variables and polynomials, respectively
- Solve: exports a function solve that tries to find a solution for the constrains
two flags can be set when creating an empty environment to activate debug mode and some invariants verification
implementation is fully functional, incremental and backtrackable
linear optimization is not supported yet
