/// \brief  Uncalibrate the, to mimic PMT jitter
///
/// \author James Sinclair <j.sinclair@sussex.ac.uk>
///
/// REVISION HISTORY:\n
///   08 Oct 2015 : J. Sinclar - First version. Smears already-calibrated times.
///
///  \details  This effectively uncalibrates the PMT hit times, by a given amount (sigma).
///            Unlike UnCal which smears pre-calibrated times during the conversion from
///            ADC to ns, this smears the post-calibration hit times. Originally developed
///            for TELLIE accuracy requirement tests.
///
///            Sigma sets the size of the of the Gaussian smearing to be applied.An offset for each PMT is then
///            randomly selected from the gaussian once at the start, this off set is then added to every hit
///            in the run for each PMT, to mimic the calibration being a bit off for each PMT.
