Add Meijaard2007FullModel that includes the equations for wheel angle, yaw, and lateral position

[moorepants]

The current Meijaard2007Model is the reduced model that has the ignorable coordinates eliminated. Differential equations can be added for the ignorable coordinates so that you can then integrate them to get the absolute position and orientation of the model in space. I do this here: https://github.com/mechmotum/bicycle-kickplate-model/pull/36/files and that can be used as the start of the code to extend the model we have.
