Corrections and Clarifications to the ODE labs in Vol4
A simple typo fix.
Fixed a formula error and removed a problem that would be hard to grade.
Cleared up a notational conflict on how to apply the initial conditions
and how to apply different higher-order ODE solving methods.
Added a *very* brief explanation tying the IVP solving methods to
numerical quadrature.
