Interface ICpuTimeProvider

public interface ICpuTimeProvider
Interface that analyses should implement if they provide information on the amount of time a certain TID spends on the CPU. This will cause this analysis to be picked up at creation and added to the model for the host. NOTE to developers: this interface is used with the composite host model but won't be necessary anymore once the analyses populate the model directly.
