Initial Android UI

UI skeleton to implement BAS generation on Android.  The layout and
interaction have been implemented, but file I/O, graphics, and data are
stubs.
Database

Implemented database interaction to store generated samples.
Bug fix in Generate Sample

Reads the n-digits in correct order
Timestamp for new entries

Populate the timestamp field when creating a new row in the database
Added study name to DB

Added  a field to the database to indicate to which study a sample point
belongs (all points stored in a single database); also updated the
layout to accept input from the user (still need to actually scrub the
input string)
Connected the Load menu item

Connected the Load menu item to the database: now populates with unique
values from the "study" field of the database.
Formatted list and comments

Created list display of items in the database for the selected study
with custom layout; augmented comments and revised variable names
GIT Ignore for generated files

Add a .gitignore file based on the one recommended on GITHub for Android
(https://github.com/github/gitignore/blob/master/Android.gitignore)
