ArgumentParser
Utility class to parse commandline argument. Each argument is in the form of -pattern param, and the programmer can supplied a default value for each parameter. Please note that the pattern is case insensitive prefix matched, so pattern -dir will match "-directory" "-DIRECT". Please design your commandline argument pattern with different prefix.
