POMDPTools upgrade instructions

Instructions for upgrading a package to use POMDPTools

1. Go to the github page of the package that you are upgrading

2. Fork the repository

3. Clone the repository to your machine

4. Make the changes

   1. Add POMDPTools to the package dependencies using the pkg> mode of the REPL

   2. Find and Replace all references to old packages within .jl and documentation files

      • Look for POMDPModelTools, BeliefUpdaters, POMDPPolicies, POMDPSimulators, and POMDPTesting

      • Check within both src and test and in documentation

      • Usually this is as simple as replacing `using POMDPModelTools` with `using POMDPTools`, etc.

   3. Remove dependencies on the old packages using the `rm` command in the pkg> mode of the REPL

   4. In the Project.toml file, add `POMDPTools = "0.1"` to the `[compat]` section, and increment the last digit in the package's version number

5. Run the project's tests in the REPL pkg> mode (check that the tests pass and that there are no deprecation warnings about old packages)

6. Push your changes (usually `git commit -a -m "upgraded to POMDPTools" && git push`)

7. Create a pull request to the JuliaPOMDP repo that you forked from

8. Move the card to the "Waiting on Zach" column in the Kanban if you have permission (reference your PR in the issue if you know how to do that)
