Subject: Switch state machine transitions to increment
X-Git-Url: https://the.earth.li/gitweb/?a=commitdiff_plain;h=fb126acc7d712c6495a2039a451b06b49e0197b2;p=temper-clone.git

Switch state machine transitions to increment

Rather than explicitly setting the next state just increment
the current state - makes it easier to add extra states.
