Applied Maths Workshop: Rose -- Building explicit symplectic numerical integrators

Our speaker for week is Danya Rose.  

Explicit integrators are desirable for their low execution costs compared to implicit
schemes.  Symplectic integrators for Hamiltonian systems are desirable for their
preservation of invariants of motion and "good behaviour" over long time integrations.
We will be introduced to symplectic Euler, composition of symplectic maps and finally a
way to build an explicit symplectic integrator of arbitrary even order.
