3 counters: separated score and test counters + permutation counter
tests sp-mi and sp-x2: proper internal parameter alpha=1
(bug) tests "mc-mi-g" and "smc-mi-g": added a strict parameter (strict = !learning) necessary to call cmig.test(fast.pcor())
Added the IAMBFDR algorithm from Pena (2008).
Added MB + PC filtering methods as local search algorithms (learn.nbr()): "gs.pc", "iapc", "fast.iapc", "inter.iapc" and "fdr.iapc"
cpquery/cpdist : new "exact" inference method
mmpc : backtracking fix (now as in Tsamardinos optimisations 6.4 and 6.5)
mmpc : always use optimized version
cpquery/cpdist: set evidence=TRUE as default value
