    Profile class.  It is a "friend" of that class, and imports data either
    by direct access to members of Profile class, or by reading in a dictionary
    that was emitted (via marshal) from the Profile class.

    The big change from the previous Profiler (in terms of raw functionality)
    is that an "add()" method has been provided to combine Stats from
    several distinct profile runs.  Both the constructor and the add()
    method now take arbitrarily many file names as arguments.

    All the print methods now take an argument that indicates how many lines
    to print.  If the arg is a floating point number between 0 and 1.0, then
    it is taken as a decimal percentage of the available lines to be printed
    (e.g., .1 means print 10% of all available lines).  If it is an integer,
    it is taken to mean the number of lines of data that you wish to have
    printed.

    The sort_stats() method now processes some additional options (i.e., in
    addition to the old -1, 0, 1, or 2).  It takes an arbitrary number of
    quoted strings to select the sort order.  For example sort_stats('time',
    'name') sorts on the major key of 'internal function time', and on the
    minor key of 'the name of the function'.  Look at the two tables in
    sort_stats() and get_sort_arg_defs(self) for more examples.

    All methods return self, so you can string together commands like:
        Stats('foo', 'goo').strip_dirs().sort_stats('calls').                            print_stats(5).print_callers(5)
