added luksan/ directory, which will eventually contain several routines written by Prof. Luksan and made available under the LGPL. currently, I've converted the PLIN.FOR subroutine, which is a reimplementation of the LBFGS algorithm (and removed the lbfgs/ directory, since the code turns out to be non-free) darcs-hash:20070903193815-c8de0-7428452045bf7147a8424cbd56af89de2e3efa66.gz

add options to use either original Fortran-derived DIRECT code or new C version, use 1e-4 magic epsilon parameter of Jones, dynamically set max #func evals in direct code and increase defaults, and add another performance hack to cdirect darcs-hash:20070829061939-c8de0-1294a9cc044efa3cb7b13e65aae18b45e18d1237.gz

performance hack: exploit the fact that the x coordinates (diameters) of the hull in DIRECT fall into only a few different values (although this may change in future modifications); also, we weren't handling the case of equal (x,y) points correctly in the hull code darcs-hash:20070829052435-c8de0-4d2204875b3f788d8884aa57f55cc76a5907bace.gz

saner memory management (and better performance), improved handling of case when no potentially optimal rects are found (choose largest rect with smallest function val, greatly improving many test cases!) darcs-hash:20070829044508-c8de0-635e1db270782d6b6741c27994cdc596c4cdde2c.gz

use red-black tree in cdirect instead of repeatedly resorting ... convex_hull is still O(N), though, and needs to be changed to a dynamic-hull algorithm to reduce the overall complexity below O(N^2), ugh darcs-hash:20070827144928-c8de0-1d7b7b1b20a5f1ca81fc7e9b31a79ee2bd4479c8.gz
