Revision history for Perl extension RPi::WiringPi::Core.

0.06 UNRELEASED
        - moved arg validation out of Core and into upper-layer client
          software. The idea is to keep this module as close to the C code
          as possible, so if this module is used directly, C will handle the
          problem
        - wrote custom physPinToWpi() C function, and added a phys_to_wpi()
          caller
        - we now shift off the object or class name if it is present in all
          sub calls
        - all parameter error handling out, and put it into the upper layers...
          we now pretty much call the C functions directly with little overhead

0.05    2016-08-11
        - added all of the wiringPiDev shared library LCD functions, and
          mapped them in ::Core

0.04    2016-08-10
        - wiringPiSetupPhys() has been implemented
        - added piBoardRev(), wpiPinToGpio(), physPinToGpio() and pwmSetRange()
          functions
        - added Perl->C mappings in POD

0.03    2016-08-10
        - added repo info to Makefile.PL
        - added get_alt(), maps to C getAlt(). This returns the current mode
          of a pin. Why it's not called getMode() is beyond me ;)

0.02    2016-08-10
        - added notices to POD
        - added POD for pwm_write()

0.01    2016-08-10
        - separated out from RPi::WiringPi
        - most core and system functions implemented
