This program was written to send one string of text as numerous text messages through a gmail account.
THIS REQUIRES A GMAIL ACCOUNT FOR THIS TO WORK.
Also make sure there is a providers file in the same folder as gmail.py and annoy.py
The information needed for the providers.txt file can be found at:
https://en.wikipedia.org/wiki/List_of_SMS_gateways

An example of the format of the providers.txt:
att=@txt.att.net

To correctly use the GUI, just hit enter after you have filled in the text box. After enter is pressed on the last text box,
the program will run, and once it is finished the GUI will close.
