TABS.  Record/Trends/History.  Different plots for each conversation
measure.  In history, conversation data is displayed in text because I
can't get the bar chart to work.  The datepicker widget is not resizable
so I need to find a suitable replacement for selecting trend ranges. 
There is a seekbar there right now that I will replace.  Still randomly
generating conversations.  If there are zero conversation upon start up,
it will crash because of null pointer (easy fix)
