adds find_ncbi_targets option to the splitter section, so NPR computation can be restricted to broken clades automatically
little addon to dump alg for the first iter
ncbi tools as optional requirement
allows to dump alg in pipelines without tree building step
added missing module
dump realnames in alignment
nprdump provides per clade difference between iterations
better target clade reporting. Dump trimmed alignment of root node
allows to run the pipeline with less than 4 species, produccing dummy trees
