Fixed the name of fort_arrange.f90
Fixed error in interchange sort

Fixed error in interchange sort comming from calling minloc without a
dim value.  This causes minloc to return a length one vector, not a
scalar.
Update README

Changed README to reflect the fact that the BLAS depencancy will not be
removed.
Adopted assumed shaped arrays

The code has been chagned to use assumed shaped arrays this
significantly increaed run time when sorting may small lists on Intel
Fortran and had little effect with gfortran.
