* Opens and reads the contents of the dictionary file specified in fileName. The file is

* mapping per line. Each line contains a key and its translation separated by a tab.

* Note: The dictionary file is assumed to be sorted by the keys in ascending order.

*

* For each line in the dictionary file, an entry is added into wordList. The entry is a String

* array of length 2, where the value of index 0 is the key and the value of index 1 is the

* translation.

*

* When opening the file, any FileNotFoundException is caught and the error message

* "Exception: File 'fileName' not found." followed by a new line is output,

* where fileName is the name of the file that the method attempted to open.

*

* @param fileName

* @param wordList Reference to ArrayList to contain the translation mappings.

* @throws IOException if an I/O error occurs when closing the file. FileNotFoundException is

* caught when opening the file.
