Calculation "health check" feature

[timmyte]

In order to check if a calculation completed successfully, we usually do need to look for certain strings in the output. The same also applies for common causes of failure.
We could create a list of known and common errors and search for string indicating these in .out and .err (if exists) and return a kind of checklist.
This could help the end user to semi-automatically determine the cause of failure.
