Bytes&Shorts Buffer & Data; Updated File Info; layout-textViews

Byte Buffer -
- BTService returns bytes to MainActivity :: 2 bytes = one value =
value is saved as a type short

Updated File Name & Information:
-> Still not complete in terms of our goal, but it's better than the
last version of the code
:: IMPORTANT: the way the file name is set up right now ::
--> If you save more than one during the time --> (down to the exact
minute) it will OVERWRITE the previous file saved that has the same
name (b/c it has the same date/time/etc)

All layouts have a temporary TextView in the top-left corner of the
Main Activity to denotes the screen size of the device and which
resources it is using.
--> ONLY TEMPORARY FOR TESTING :)
