glbNetworkConfig.maxDelay > 1 despite setting all delays to 1 or less

[benballintyn]

I wrote a class inheriting ConnectionGenerator to connect groups using normally distributed weights. in the connect method I explicitly set delay = 1. Despite using this custom connection to connect all groups, when trying to add STP I get the error:
[ERROR carlsim/kernel/src/snn_manager.cpp:4864] STP with delays > 1 ms is currently not supported.

This must mean that somewhere glbNetworkConfig.maxDelay must be being set to > 1 incorrectly.
