+/*### 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
+```
