Changeset 356 for trunk/src/stgen.py

Message:

Changed the behaviour of the AnalogSignal constructor. Before, t_start and t_stop were used to throw away data, on the assumption that the signal always started at t=0 - see [45]. Now, these arguments are used as metadata, and we check that they are consistent with the number of elements in the signal array.

Also added some checks that all the AnalogSignals in an AnalogSignalList are consistent in terms of length, dt, etc.
