The basic String class.
A haxe String is immutable, it is not possible to modify individual
characters. No method of this class changes the state of [this] String.
Strings can be constructed using the string literal syntax "string value".
String can be concatenated by using the + operator. If an operand is not a
String, it is passed through Std.string() first.
