This library provides a basic implementation of an interrupt timer driven software serial port on any two digital GPIOs as RX/TX.
Notes: Import SparkIntervalTimer library (by Paul Kourany) Due to limited free timers and to avoid interrupt mashup, only one active instance is allowed. Soft RX pin needs to be interrupt enabled, so on Photon D0 & A5 won't work as RX
