 //                 Bestarrange.cc
 // Builds an hierarchical clustering tree, and finds its optimal
 // leaf ordering. The program gets as an input an expression 
 // file (see README) and generates four files as output.
 // The first two (for an input file named foo.txt, these are called fooIn.GTR 
 // and fooIn.CDT) are the hierarchical clustering reuslts. The other two
 // files (foo.CDT and foo.GTR) are the optima leaf ordering results.
 // Both these results can be viewed using Michael Eisen's TreeView 
 // software.
