Resolve "Add a logging framework for command line output"

What does this MR do?

Use loggers for the entire terminal output of DORiE.

Replace config keys verbose with logLevel, taking the same names as defined by spdlog
Rename setup_inifile.hh to setup.hh and add functions:
- Setup::init initializes the MPI helper, the config file, and the base logger
- Setup::debug_hook halts the program for a debugger to hook into the program
Add logger as optional argument to most classes, such that they use a certain logger by default or the one specified by the programmer
Add developer docs on how to use the loggers

Is there something that needs to be double checked?

All DUNE output (other than exceptions) is currently suppressed. One option would be to write a stream buffer, into which the output of functions like PDELab::mark_grid is stored. This storage could then be accessed and displayed via a logger at a certain log level setting.
