argchecker is used in few places and could be replaced with Params::Validate

[Dan MacNeil]

cdw
grep -i argcheck . -r

perldoc MVHub::ArgChecker

Every place ArgChecker::check_args() is used (and there are not many places), there is a better alternative in Params::Validate

Replace calls to arg_checker , remove the library and test file
