poisson_generator – Generate spikes with Poisson process statistics
===================================================================

Description
+++++++++++

The ``poisson_generator`` simulates a neuron that is firing with Poisson
statistics, that is, exponentially distributed interspike intervals. It will
generate a `unique` spike train for each of its targets. If you do not want
this behavior and need the same spike train for all targets, you have to use a
``parrot_neuron`` between the poisson generator and the targets.

rate
  Mean firing rate (spikes/s)

Set parameters from a stimulation backend
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The parameters in this stimulation device can be updated with input
coming from a stimulation backend. The data structure used for the
update holds one value for each of the parameters mentioned above.
The indexing is as follows:

 0. rate
