+/*### Bank OCR
+
+Your manager has recently purchased a machine that assists in reading letters and faxes sent in by branch offices. The machine scans the paper documents, and produces a file with a number of entries. You will write a program to parse this file.
+
+#### Specification
+#### User Story 1
+
+The following format is created by the machine:
+```
+    _  _     _  _  _  _  _
+  | _| _||_||_ |_   ||_||_|
+  ||_  _|  | _||_|  ||_| _|
+```
+Each entry is 3 lines long, and each line has 27 characters. 3 lines of each entry contain an account number written using pipes and underscores.
+
+Each account number should have 9 digits, all of which should be in the range 0-9. A normal file contains around 500 entries.
+
+Write a program that can take this file and parse it into actual account numbers.
+
+Example input and output
+```

+Given a person's allergy score, determine whether or not they're allergic to a given item, and their full list of allergies.
+An allergy test produces a single numeric score which contains the information about all the allergies the person has (that they were tested for).
+The list of items (and their value) that were tested are:
+    eggs (1)
+    peanuts (2)
+    shellfish (4)
+    strawberries (8)
+    tomatoes (16)
+    chocolate (32)
+    pollen (64)
+    cats (128)
+So if Tom is allergic to peanuts and chocolate, he gets a score of 34.
+
+Now, given just that score of 34, your program should be able:
+    To say have Tom allergic to specific product or not.
+    To give list of all allergens Tom is allergic to.
+
+E.g. it can be class with methods IsAllergicTo(string), List() and receiving allergyScore in constructor
+
+Note: a given score may include allergens not listed above (i.e. allergens that score 256, 512, 1024, etc.).
+Your program should ignore those components of the score.
+For example, if the allergy score is 257, your program should only report the eggs (1) allergy.
