It'd be great to get the basic steps for doing a build from start to end documented.

In particular the details for generating the libsqlcipher_android-XX.so would be very useful (I'd really like to fix the 2.1 issue i reported earlier, but can't get the end to end build going)

We will continue to fill this out with a bit more descriptive text, but this should do for now.
