 The present package makes one major assumption: E-features are more meaningful if they are coming from a set of traces rather than a single trace. And they are even more meaningful if these traces come from different cells of the same cellular type.
 This assumption dictates the organisation of the package and has several consequences:
 
-The efeatures extracted through the package will always be averaged over the trace considered. For example, the AP_amplitude will be an average over all the action potentials present in a trace. If you wish to work on an AP by AP basis, please consider using the eFEL library directly.

 A large part of the present software is therefore dedicated to averaging the features across set of "equivalent" recordings. To be able to average e-features across different cells in a meaningful way, an equivalence must be established between the traces coming from these different cells. It would not make sense to average the mean firing frequency obtain cell A on a 1s long step protocol with the one obtain for cell B on a ramp protocol that lasts for 500ms. We chose to define recordings as equivalent based on two criteria: (1) They have the same name and (2) they are of the same amplitude when the amplitude is expressed as a percentage of the rheobase of the cell.
