'**SUMMARY**
Save the calibration matrices to file. The file name should be without the extension.
The default extension is .xml.
**PARAMETERS**
* *filename* - The file name, without an extension, to which to save the calibration data.
**RETURNS**
Returns true if the file was saved , false otherwise.
**EXAMPLE**
See :py:module:calibrate.py'

def saveCalibration(self, filename):

    if (type(self._calibMat) != cv.cvmat):
        logger.warning("FrameSource.saveCalibration:    No    calibration    matrix    present,    can't    save.")
    else:
        intrFName = (filename + 'Intrinsic.xml')
        cv.Save(intrFName, self._calibMat)
    if (type(self._distCoeff) != cv.cvmat):
        logger.warning("FrameSource.saveCalibration:    No    calibration    distortion    present,    can't    save.")
    else:
        distFName = (filename + 'Distortion.xml')
        cv.Save(distFName, self._distCoeff)
    return None
