Tidy indentation
CHANGES TO TPulseIsland !!!:
 - Change GetSamples signature as discussed in issue #171
 - Add new constructor to copy an existing waveform vector between two iterators
 - Add Setters for TPI contents
 - Increment ClassDef
Change the way PulseCandidateFinder returns candidate pulses.  The caller only
needs to delete the vector once the method won't be called again.
Check if current size is less than OR EQUAL to pulse index
Make sure to reset pulses that are left over in the pulse list
Big tidy up of FirstCompleteAPGenerator and use the Pulse finder properly
Plot TPIs in terms of clock time, not real time
Extra safety checks in PlotPedestalAndNoise and reduce binning
