WIP: Implemented basic mark rounding algorithm.

Removed RacePosition class. Instead marks are just grabbed from the mark order class when necessary.
No marks are stored as an attribute in the yacht class but the 'currentMarkSeqID' which is used to get current, and surrounding marks.
Works for all marks in between but not including starting and finishing gate as no angle can be made with them. Still to work out how to implement this
