Better rendering of doubles and floats in cout

This release improves printing of floating point numbers in cout.

Re-release with SAMD support (and fixed library file)

v0.1.4

Remember to update the version in the next release

Add samd support.

This release adds samd to supported architectures.

Support for USB serial platforms.

This release fixes problems with platforms that use USB serial ports (like SparkFun Pro Micro). It's tested on a Teensy 2.0. Teensy's compiler is stricter than Arduino's. There are fixes for that too.

Working for Fall 2016

This release is for the CS-11M class in the fall of 2016. It's the same code used by last year's class with success. I have used a newer version of uClibc++ and I've fixed the problem where cout doesn't print floats (but does print doubles).
