v2.0.2: Patch release for compiler warnings

The only functional change in this release is to fix bug #2, which came from a GCC -Wall scan.

We also reorganized the directory structure to match the current Arduino library style, trimmed whitespace, other minor nits.

What's Changed

• Fix #2, and misc minor updates. V2.0.1-pre1. by @terrillmoore in #3
• Release v2.0.2 by @terrillmoore in #6

Full Changelog: v2.0.0...v2.0.2

Official MCCI release

Although this is backward compatible and we hate obscuring credit for libraries, the Arduino library system really demands that we diverge names from the Adafruit original. This update keeps an <Adafruit_FRAM_I2C.h> and full backward compatibility, but it also creates a pure C++ <MCCI_FRAM_I2C.h> with MCCI names.
