Initial commit to create the project

Create a sample android app which collects android sensor data and pushes it to
sMAP. This is the initial checkin so that we can start collaboration. It works
as-is, but could require additional work.

Potential enhancements:
- Improve the user interface
- Store the data in an SQLite DB instead of in the filesystem
- Make the URLs shared preferences and allow them to be editable by the user
