cont_delay_synapse – Synapse type for continuous delays
=======================================================

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

``cont_delay_synapse`` relaxes the condition that NEST only implements delays
which are an integer multiple of the time step `h`. A continuous delay is
decomposed into an integer part (``delay_``) and a double (``delay_offset_``) so
that the actual delay is given by  ``delay_*h - delay_offset_``. This can be
combined with off-grid spike times.

All delays set by the normal NEST Connect function will be rounded, even
when using cont_delay_synapse. To set non-grid delays, you must either

1. set the delay as model default using :py:func:`.SetDefaults`, which
   is very efficient, but results in a situation where all synapses then
   will have the same delay.

2. set the delay for each synapse after the connections have been
   created, which is slower, but allows individual delay values.

Continuous delays cannot be shorter than the simulation resolution.
