Slow loading

[jebej]

This package is slow to load due to its dependence on FiniteDiff and ForwardDiff. This is somewhat problematic given it should be a "lightweight" base package, especially if packages above it do not need the functionality.

Well, it's not meant to be light weight. It provides AD as one if its features for Optim and NLsolve and LsqFit. However, if you look at NLSolvers.jl which is the new backend code for Optim, you will see that I specifically left out AD for this reason. Then, Optim will include AD and NLSolvers.jl will not. So if you really need something cheap, you can use NLSolvers.jl
