introduced thread_local storage
creation of minima is performed by fc ctor now. Also direct access to minima.
no cph lambda anymore: handled directly by flow_complex
removed unused typedefs
add_point is now append_point, to make it clear that there is an order among the points of affine_hull
flow_complex cna now be queried for existing cps, without insertion
descends are not sheduled, if the cps to that would be found exist already
disabling vectorization: dynamic size overhead too big. Maybe fixed size can help.
