Actually calculate APD.
target voltage = resting +'percentage'*(amplitude-resting).
APD is taken to be the time from when the target voltage is crossed upwards to the time voltage crosses the target voltage downwards.
percentage | The percentage of the amplitude to calculate for. |

std::vector< double > CellProperties::GetRestingPotentials | ( | ) |
Returns the minimum resting potential BEFORE each AP.
These are calculated as the point where the derivative of the potential is lowest, i.e. when the profile is flattest in between two APs.
Or just the minimum voltage before an upstroke if we can't find a flat bit.
So this vector should be the same length as the other AP property vectors.
