+'''Hello Fellows,
+
+Write a program to read through the mbox-short.txt and figure out the distribution by hour of the day for each of the messages. 
+You can pull the hour out from the 'From ' line by finding the time and then splitting the string a second time using a colon.

+*************************************************************************************************************
+
+Instructions
+If you don't already have it, install the SQLite Browser from http://sqlitebrowser.org/.
+
+Then, create a SQLITE database or use an existing database and create a table in the database called "Ages":
+
+CREATE TABLE Ages ( 
+  name VARCHAR(128), 
+  age INTEGER
+)
+Then make sure the table is empty by deleting any rows that you previously inserted, and insert these rows and only these rows with the following commands:
+
+DELETE FROM Ages;
+INSERT INTO Ages (name, age) VALUES ('Malakhy', 37);
+INSERT INTO Ages (name, age) VALUES ('Marlee', 23);
+INSERT INTO Ages (name, age) VALUES ('Timucin', 18);
+INSERT INTO Ages (name, age) VALUES ('Anneroy', 17);
+Once the inserts are done, run the following SQL command:
+SELECT hex(name || age) AS X FROM Ages ORDER BY X
+Find the first row in the resulting record set and enter the long string that looks like 53656C696E613333.
+Note: This assignment must be done using SQLite - in particular, the SELECT query above will not work in any other database. So you cannot use MySQL or Oracle for this assignment.
