/**
 * Class TestSmp is a unit test main program for classes {@linkplain

 * edu.rit.compbio.seq.ProteinLocalAlignmentSmp}. The program reads in a query
 * sequence and a subject sequence, aligns them in a parallel thread team, and
 * prints the alignment.
 * 

 * Usage: java -Dpj.nt=K edu.rit.compbio.seq.test.TestSmp
 * queryfile subjectfile
 * 
K = Number of parallel threads
 * 
queryfile = Query sequence file
 * 
subjectfile = Subject sequence file
