/**
 * Class Test04 is a unit test program for classes {@linkplain
 * edu.rit.compbio.phyl.DnaSequenceList}, {@linkplain
 * edu.rit.compbio.phyl.DnaSequenceTree}, {@linkplain
 * edu.rit.compbio.phyl.FitchParsimony}, and {@linkplain
 * edu.rit.compbio.phyl.Upgma}. The program:
 * 

 * 

 * Reads a {@linkplain DnaSequenceList} from the input file in interleaved
 * PHYLIP format.
 * 

 * Constructs a phylogenetic tree using the UPGMA algorithm.
 * 

 * Computes and prints the tree's Fitch parsimony score.
 * 

 * Reorders the list of DNA sequences into descending order of branch length and
 * stores the list in an output file.
 * 

 * Stores a picture of the tree in an output file as a serialized {@linkplain
 * edu.rit.draw.Drawing} object.
 * 
 * 

 * The {@linkplain View} program can be used to view the drawing file and
 * save it in an image file in several formats.
 * 

 * Usage: java edu.rit.compbio.phyl.test.Test04 infile outfile
 * drawfile [ format ]
 * 
infile = Input DNA sequence list file name
 * 
outfile = Output DNA sequence list file name
 * 
drawfile = Output drawing file name
 * 
format = DecimalFormat string for branch lengths (default:
 * "0.00")
