/*!
AbstractProcessStep is a convenience class, which can be used as a base class instead of BuildStep.
It should be used as a base class if your buildstep just needs to run a process.
Usage:
Use setCommand(), setArguments(), setWorkingDirectory() to specify the process you want to run
(you need to do that before calling AbstractProcessStep::init()).
Inside YourBuildStep::init() call AbstractProcessStep::init().
Inside YourBuildStep::run() call AbstractProcessStep::run(), which automatically starts the proces
and by default adds the output on stdOut and stdErr to the OutputWindow.
If you need to process the process output override stdOut() and/or stdErr.
The two functions processStarted() and processFinished() are called after starting/finishing the process.
By default they add a message to the output window.
Use setEnabled() to control wheter the BuildStep needs to run. (A disabled BuildStep immediately returns true,
from the run function.)
