    \brief The RunConfiguration class is the base class for a run configuration.

    A run configuration specifies how a target should be run, while a runner
    does the actual running.

    The target owns the RunConfigurations and a RunControl will need to copy all
    necessary data as the RunControl may continue to exist after the RunConfiguration
    has been destroyed.

    A RunConfiguration disables itself if the project has no parsing
    data available. The disabledReason() method can be used to get a user-facing string
    describing why the RunConfiguration considers itself unfit for use.
