""" Shorter:
        How about a optimizing tool for your python project that keeps track of
        the number of times you called a specific function and the total time the
        function took.

    Short:
        @analyze_number_of_calls decorator adds functions to a hidden dictionary
            object which tracks numbers of their calls in your application.

        @analyze_time_of_execution decorator gets total number of seconds the function
            took to execute.

        This way you can keep track of which functions in your application should
        be optimized.

        print_analysis() prints out functions ordered by their call number and time took
        restart_analysis() clears the dictionary and starts analysis from the start
