+Integrals.jl is an instantiation of the SciML common `IntegralProblem`
 interface for the common quadrature packages of Julia. By using Integrals.jl,
 you get a single predictable interface where many of the arguments are
 standardized throughout the various integrator libraries. This can be useful
