Plots the stable and unstable manifolds of a saddle point. A search procedure is utilised to identify an equilibrium point, and if it is a saddle then its manifolds are added to the plot.

system to be analysed. Discussion of the required structure of these
functions can be found in the package vignette, or in the help file for the
function

The initial point from which a saddle will be searched for. This

The step length of the independent variable, used in numerical
integration. Decreasing the absolute magnitude of

The final time of the numerical integration performed to identify the manifolds.
