Vector2 class

A vector with two components.

The Vector2 type exposes the following members:

Constructor	Description
`__init__(self, s)`	Initializes a new instance of the `Vector2` struct.
`__init__(self, s)`	Initializes a new instance of the `Vector2` struct.
`__init__(self, vec)`	Initializes a new instance of the `Vector2` struct.
`__init__(self, x, y)`	Initializes a new instance of the `Vector2` struct.
`__init__(self)`	Constructs a new instance of Vector2

Property	Description
u	Gets or sets the U component if the `Vector2` is used as a mapping coordinate. It’s an alias of x component.
v	Gets or sets the V component if the `Vector2` is used as a mapping coordinate. It’s an alias of y component.
length	Gets the length.
x	The x component.
y	The y component.

Method	Description
`dot(self, rhs)`	Gets the dot product of two vectors
`equals(self, rhs)`	Check if two vector2 equals
`cross(self, v)`	Cross product of two vectors
`normalize(self)`	Normalizes this instance.
`compare_to(self, other)`	Compare current vector to another instance.
