    Class Operations:
    =================
    The file store class stores files and paths, saving only one unique
    copy of each.  Files are stored in a map with file name key and an
    associated list of iterators pointing to the corresponding paths
    on which that file name can be found.  Paths are stored in a set
    and the file's iterator list holds iterators on that set.

    Public Interface:
    =================
    fileStor fs;               // construct an empty fileStor object
    fs.add("file1","path1");   // add file name and its path to store
    int num = fs.files();      // return number of unique files in fileMap
    int num = fs.paths();      // return number of unique paths in pathSet
    fs.display();              // show each file and its paths
    fileMap fm = fs.FileMap(); // return fileMap
    pathSet ps = fs.PathSet(); // return pathSet
