+This example creates the ピックアップ募集 Banner which ran from 2021-02-04 to 2021-02-11. The only student in the game who was **not** in This banner was ノゾミ, so you can see her being filtered out of the list of *all** students to create a list of students in the ピックアップ募集.

+After this, we want to determine which units are on rate-up if there are any. In this example, ホシノ and シロコ have increased pull rates. 
+
+The Rest of the code consists of instantiating the Gacha and Banner Structs using their respective Builders.
