Description: # A basic but fast, persistent and threadsafe caching system
        
        **Basic commands**
        
        Importing required modules first:
        
            from webscrapetools import urlcaching
         
        Initializing the cache:
        
            urlcaching.set_cache_path('.wst_cache')
            
        The option _expiry_days_ sets the cache expiry period, default is 10 days.
            
        This is a required step: otherwise responses to url calls will simply not be cached.
        Cache data are stored in the specified folder, so that re-using the same string makes the cache persistent. This creates
        the folder on the fly if it does not exist.
        The following command cleans up the cache, making sure we start with no prior data:
        
            urlcaching.empty_cache()
            
        Opening an url with the following command stores the repsonse content behind the scene, so that subsequent calls will
        not hit the network.
        
            urlcaching.open_url('http://www.google.com')
            
            
        **Full example**
        
            from webscrapetools import urlcaching
            import time
            
            # Initializing the cache
            urlcaching.set_cache_path('.wst_cache')
            
            # Making sure we start from scratch
            urlcaching.empty_cache()
            
            # Demo with 5 identical calls... only the first one is delayed, all others are hitting the cache
            count_calls = 1
            while count_calls <= 5:
                start_time = time.time()
                urlcaching.open_url('http://deelay.me/5000/http://www.google.com')
                duration = time.time() - start_time
                print('duration for call {}: {:0.2f}'.format(count_calls, duration))
                count_calls += 1
            
            # Cleaning up
            urlcaching.empty_cache()
        
        The code above outputs the following:
        
            duration for call 1: 6.74
            duration for call 2: 0.00
            duration for call 3: 0.00
            duration for call 4: 0.00
            duration for call 5: 0.00
