// Details: MI common code class. Command arguments container class.
// A command may have one or more arguments of which some may be
// optional.
// *this class contains a list of the command's arguments which are
// validates against the commands argument options string (context
// string).
// Each argument tries to extract the value it is looking for.
// Argument objects added to *this container are owned by this
// container
// and are deleted when this container goes out of scope. Allocate
// argument
// objects on the heap.
// It is assumed the arguments to be parsed are read from left to right
// in
// order. The order added to *this container is the order they will
// parsed.
