Preliminary support for LTE dynamic time-stepping based on Local truncation error. This enables the possibility to connect a capacitor between ground and a TTL output and get a e.g. 100 ns delay with a 1nF capacitor.
Added an example circuit (cdelay.c) Changed the log device to support nano-second granularity. LTE is not yet enabled due to it's ugly test-state.
