30	@file
31	@brief Declaration of the MultiType and some helper constructs.
32
33	The MultiType can hold a value of one of the following types:
34	- all primitives
35	- all pointers
36	- string
37	- Vector2, Vector3, Vector4
38	- Quaternion
39	- ColourValue
40	- Radian, Degree
41
42	The MultiType has a "type" determined by the first assigned value, either through
43	- the constructor,
44	- the assignment operator= or
45	- setValue(value).
46	If you assign another value of another type, the MultiType keeps "it's" type and
47	converts the new value to this type.
48
49	If you want to change the type, there are three possibilities:
50	- convert<T>() set's the type to T and converts the currently assigned value
51	- setType<T>() set's the type to T and resets the value
52	- setValue<T>(value) assigns a new value and changes the type to T.
53
54	@example
55	MultiType a = 10;; // a has now the type int and the value 10
56	a.setValue("3.14"); // a has still the type int and "3.14" gets converted, therefore the value is now 3
57	a.setValue<float>("3.14"); // a has now the type float and "3.14" gets converted to 3.14
58	a.convert<bool>(); // converts 3.14 to bool, which is true
59	a = false; // assigns false, this is equivalent to a.setValue(false)
60
61	@note
62	Whenever a value gets converted, there is a boolean return value telling you whether it was
63	successful or not. If it wasn't a zero value is assigned with the help of zeroise<T>().
