Module coords

Exposes information about point coordinates

Curve by default does not require that points expose their coordinates. Some curves implementations intentionally don’t expose points coordinates, and, generally, most of the EC algorithms don’t need them. Each curve implementation may optionally expose affine coordinates by implementing trait from this module.
