Solves the discrete function map defined by
prob using the algorithm
alg. If no algorithm is given, a default algorithm will be chosen.
The implementation for solving discrete equations is the
FunctionMap algorithm in OrdinaryDiffEq.jl. It allows the full common interface (including events/callbacks) to solve function maps, along with everything else like plot recipes, while completely ignoring the ODE functionality related to continuous equations (except for a tiny bit of initialization). However, the
SimpleFunctionMap from SimpleDiffEq.jl can be more efficient if the mapping function is sufficiently cheap, but it doesn't have all of the extras like callbacks and saving support (but does have an integrator interface).

FunctionMap: A basic function map which implements the full common interface.
OrdinaryDiffEq.jl also contains the
FunctionMap algorithm which lets you It has a piecewise constant interpolation and allows for all of the callback/event handling capabilities (of course, with
rootfind=false. If a
ContinuousCallback is given, it's always assumed
The constructor is:
Every step is the update
If in addition
scale_by_time=true, then every step is the update
Notice that this is the same as updates from the Euler method, except in this case we assume that its a discrete change and thus the interpolation is piecewise constant.
SimpleFunctionMap: A barebones implementation of a function map. Is optimally-efficient and has an integrator interface version, but does not support callbacks or saving controls.
