findNearestPoint

A list comprised of x coordinates, y coordinates, such as output by <code>pointsToList</code>. Should represent the attractors of <code>fun</code>.

points

An epsilon, expected to already be squared, used to determine when a point is close enough. Only important if <code>deep</code> is true.

If true, only return a point if it is within epsilon distance. Otherwise, return the closest point.

deep

Determines which point in a list is closest to the input. 0 is used if all are further from epsilon.

internal

An expressive language to facilitate simulation and visualization
of two-dimensional dynamical systems. The basic elements of the language are
a model wrapping around a function(x,y) which outputs a list(x
= xprime, y = yprime), and a range. The language supports three
types of visual objects: visualizations, features, and backgrounds. Visualizations, including dots and arrows,
depict the behavior of the dynamical system over the entire range.
Features display
user-defined curves and points, and their images under the system.
Backgrounds define and color regions of interest, such as basins of attraction.
The language
can also approximate attractors and their basins through simulation.

findNearestPoint: Determines which point in a list is closest to the input. 0 is used if all are further from epsilon.
