According to project structure discussed with Andrew. We want to flatten out the hierarchy and minimize the number of GYP files. No changes at all are being made in the source files; they are just moved. The only modified files are the GYP file and Android.mk Kevin: I updated relative paths in Android.mk so please verify it is correct, since I don't know how to build that.
