Macro cprintln 

macro_rules! cprintln {
    ($title:expr, $msg:expr => $color:ident) => { ... };
    ($title:expr, $msg:expr => ($r:expr, $g:expr, $b:expr)) => { ... };
    ($title:expr, $msg:expr) => { ... };
    ($msg:expr => $color:ident) => { ... };
    ($msg:expr => ($r:expr, $g:expr, $b:expr)) => { ... };
    ($msg:expr) => { ... };
}

Same as cprint! but with a newline at the end.
