SDG 18th biweekly report

Review of the past two weeks

In the last two weeks, my work can be summarized as two parts: Continuing the integration of DifferentiationInterface.jl in BoundaryValueDiffEq.jl and add more documentations.

1. The last several weeks on integrating DifferentiationInterface.jl to BoundaryValueDiffEq.jl is almost done in PR Use DifferentiationInterface for the jacobian, feat: access overloaded inputs from preparation result.

2. Continued the revamp of documentation, including the individual documentatoin n DiffEqDocs.jl one, details can be checked on corresponding pull request: Add documentations and Revamp BVP docs for new features.

3. Implemented an interface package BVPInterface.jl for porting Fortran BVP solvers into SciML universe, now it ports BVPM2, BVPSOL, COLSYS, COLNEW, COLDAE, and COLMOD, more solvers will be implemented in the near future.

More TODOs:

1. Complete the PR for refactoring BoundaryValueDiffEq.jl from SparseDiffTools.jl to DifferentiationInterface.jl

2. Start working on the implementation of infinite final time BVP solver, and will start on this when the above feature is done.
