// This function library dynamically links the ADSmartIO library
// and library functions.
//
// Differences from documentation
// - Spelling
//     SIOBackLightVEEPwm -> SIOVeePwm (documentation is correct, .h file was not)
//     SIOBackLightPWM -> SIOBacklightPWM
//     SIOBackLightON -> SIOBacklightOn
//     SIOBackLightOFF -> SIOBacklightOff
//     SIOSetKeyPadSize -> SIOSetKeypadSize
// - Omitted
//     version 0x8003 functions
//

// Loads ADSmartIO library and maps function names to functions in
// the library.  Returns false if the library is not found.
