function out=RPI_softPwmCreate(pin,ival,pwmrange)
// Function to set up software pwm on a given pin
//
// Calling Sequence
//  RPI_softPwmCreate(pin,ival,pwmrange)
//
// Parameters
//  pin     : pin to start software pwm on. Numbering sequence to follow as initiated using RPI_pinNumbering function
//  ival    : inital value
//  pwmrange: range for the pwm
//
// Description
//  This function creates a software controlled PWM pin. Any GPIO pin can be used. Using 100 for the range, the value can be anything from 0 (off) to 100 (fully on) for the given pin.
//
//The return value is 0 for success. Otherwise the global error number variable should be checked to see what went wrong.
//
// Examples
//  RPI_softPwmCreate(1,25,250)
