Calibration.cpp return-statement with a value, in function returning 'void'

[Dario Longobardi]

Hi @kylemcdonald,

with debian stretch and g++ version 4.9.2-10 one of function undistort, return-statement error,
because it tries to return a boolean, but it has been declared as a void.

I have modified these files to solve:

ofxCv/libs/ofxCv/include/ofxCv/Calibration.h line 74

bool undistort(cv::Mat img, int interpolationMode = cv::INTER_LINEAR);

ofxCv/libs/ofxCv/src/Calibration.cpp line 402

bool Calibration::undistort(Mat img, int interpolationMode) {
        if(img.rows != undistortMapX.rows || img.cols != undistortMapX.cols){
            ofLog(OF_LOG_ERROR, "undistort() Input image and undistort map not same size");
            return false;
        }
        img.copyTo(undistortBuffer);
        undistort(undistortBuffer, img, interpolationMode);
        return true;
}

maybe it can be useful, greetings!

Dario
