This application demonstrates the data usage chart from the Android Open Source
Project (AOSP). The original source for the chart can be downloaded from:

https://android.googlesource.com/platform/packages/apps/Settings/

The version of the source in AOSP is tightly coupled to the NetworkStats classes
that are private. Additionally, the source code references many other hidden
methods and resources.

This version of the chart is decoupled from AOSP. The primary chart is now
a bar chart. The date sweeps were enhanced to show the dates in a "flag" at
the top of the sweeps. The warning and limit horizontal sweeps were removed
and an average sweep was added.
