added some type hints
apply-ruleso generates al possible solutions of the rule application
added core.logic equivalents of transform-expression
now reworking solve-system
solve-systems can now handle multiple solutions
fixed bug in report solution of solve-linear-system where a leading one was not recignized when not in diagonal position
solve-linear-system uses the same format as solve-system and can deal with to few arguments to solve for
minor updates
added special case solvers for polynomials
solve dispatches now to different solving strategies which can be arbitrary core.logic relations
solve system is now capable of solving the equations on http://reference.wolfram.com/mathematica/ref/Solve.html
performance improvements through creating lists with (into '() ....) instead of (list* ....)
removed some unnecessary code
started restructuring for first release. still failing tests
updated core api for solve
Merge branch 'solve' of https://github.com/clojure-numerics/expresso into solve
fixed tests after restructuring
prepare for first release
