pick fragments in a single window

nfrags – number of fragment pieces to be picked
target_seq – query sequence and this also defines fragment length, such as 3mer or 9mer
target_ss – secondary structure of query sequence.
seq_weight and ss_weight – weight for sequence match and secstruct match
exclude_* – exclude such squence pattern when picking fragments
library – output as a collection of fragments for that residue window

scan through vall database, for each position within each window, if sequence does not match target sequence, penalize by seq_weight; if secstruct does not match target secstruct, penalize by ss_weight. In the end, picking top "nfrags" fragments with lowest penalty score (this internally uses a "heap" implementation).SEE ALSO THE DUPLICATE COPY BELOW WHICH INCLUDES FILTERING BY TARGET TORSION ANGLES IE, IF YOU FIX A BUG HERE FIX IT DOWN THERE AS WELL (THANKS)
