// 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 assummed 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.
// Gotchas: None.
