This class parses command line input or string input to extract the
multi_id, detector_id, command and arguments. It's used in the command
line binaries (sls_detector_get/put) to parse commands and in the
slsDetectorShared library to parse input from config files.

This class is fully internal to the project and NO guarantees are given
on the stability of the interface or implementation. This is also the
reason that the header file is not exposed.
