Executes a Local Alignment Action where searchSeq is the Nuleotide Sequence to align
with all possible Precursor Sequences (dbSeq) in the miRNAdatabase
Executes exact Pattern Matching where the pattern is maybe a (part of) precursor description and
the text is the desciption of a Precursor in a miRNA databse
Predicts Position of mature miRNA on instrinsic data 1) calculating the
avarage value of all precursors 2) finding the minimal value (relative to
alignment) !
