Application
    dirToString

Description
    Converts a directory path into a camelCase string.
    e.g. dir1/dir2/dir3 becomes dir1Dir2Dir3

Usage

    e.g.
        using sh
        baseDirName=$(echo $dir | $bin/dirToString -strip)

        using csh
        set baseDirName=`echo $dir | $bin/dirToString -strip`
