Currently, the GitRepositoryMiner logs the runtime of the mining process to the console log only:

[Forensics] Creating SCM miner to obtain statistics for affected repository files
[Forensics] -> Git miner successfully created in working tree '/var/data/workspace/Forensics'
[Forensics] Analyzing the commit log of the Git repository '/var/data/workspace/Forensics'
[Forensics] -> created report for 697 files in 41 seconds

It would be nice if this information would be stored in the RepositoryStatistics instance as well. This feature should require a change in the model object only. Steps to do:

• Record the current time stamp (see GitRepositoryMiner) when the RepositoryStatistics instance is created (constructor)
• Update the total runtime whenever a new modifying operation has been invoked on the instance (all add methods)
• Visualize the total time in the user interface
