Congealing Commandline Wrapper

CongealingCLI is a wrapper to access the Congealing Un-biased Groupwise Registration tool. It is now possible to generate a configuration file for Congealing by using a GUI or command line arguments. In fact, by not specifying any arguments and just running the wrapper, a default configuration file for congeal is generated.

Using --launch

When adding a --launch PATH_TO_CONGEAL_EXEC, the congeal executable gets launched rather than printing the path to the generated configuration file.

For example

$ ./CongealingCLI --launch congeal

starts the congeal executable with the configuration file shown above.
