DiffEqBase.jl

[!IMPORTANT]

This package was moved to be a sublibrary in OrdinaryDiffEq.jl. The migration is a maintanance change but should have no functional
change to the library.

Previous Stuff

DiffEqBase.jl is a component package in the DiffEq ecosystem. It holds the
common types and utility functions which are shared by other solver packages
to promote code reuse in the differential equation solver code.
Users interested in using this
functionality in full should check out DifferentialEquations.jl.

The documentation for the interfaces here can be found in DiffEqDocs.jl and DiffEqDevDocs.jl.
