Improvement: LaunchManager shall log real names for process groups and process group state, instead of hashes #57
Description
The IdentifierHash class is used to identify process group (states) in a memory efficient way, as an object gets also transferred between processes (e.g. via shared memory). This is why it stores only a hash value of the string which is given at construction time. However it confusing to print these hash values in log messages.
Proposal: One possible solution would be a central lookup table where the string which was used during construction time can be retrieved.
Limitations: An IdentifierHash which was constructed in process A but logged in process B will still only log its hash value, of course. From our point of view this is acceptable. As IdentifierHashs are constructed in LaunchManager, inside LaunchManager it will always output its string value.
