When an experiment is signed, a user with witnessing privileges will get a notification to witness it.
In the experiment, you have the option to witness or reject the signed experiment.
Rejecting the experiment will reject the first signature, and will enable editing of the experiment data again.
Wintessing will lock the experiment for editing, without being able to revert the signature, meaning it is locked permanently.
When choosing to revert or witness the experiment, a window will open with a comment section, that will automatically be populated with the person who signed the experiment so he will be notified of the witnessing or rejecting of the experiment.
Click "Witness" (Or "Reject")
A window will open with your user name and password, for confirming the Witnessing or rejecting process.
Click "confirm".
After witnessing the experiment, a timestamp will appear under the experiment name.
