/*********************************************************************************************
 * MainActivity Class/Activity
 * This activity takes care of the menu in the application using ActivityGroup. this is also
        where the activities for each menu item are set and started through the tabHost object.
 * A better way to go about doing this in the future would be through some sort of fragmentation
        where instead of having multiple differnet activities, you would have this main activity
        that is just fragmented into pieces so that all of the data is centralized.
