Consider adding some brief docs for MrAnderson developers

[lread]

Currently

While making some changes to MrAnderson, I was curious to know the best way to build and install locally.

I stumbled on the Makefile. And looked at what MrAnderson does for CircleCI.

And figured things out. Maybe.

I think...

Some dev docs would be helpful for those who want to contribute to MrAnderson.

This could either be in a separate dev.md doc or directly in the current README.md.

Also...

Even after looking at the Makefile several times, I'm not sure I understand how to build and install a version of MrAnderson with inlined deps to my local maven repo.

I tweaked the Makefile:

-.PHONY: install inline test integration-test deploy clean
+.PHONY: boostrap-install inline test integration-test install deploy clean

# Note that `install` is a two-step process: given that mranderson depends on itself as a plugin,
# it first needs to be installed without the plugin, for bootstrapping this self dependency.
-install:
+bootstrap-install:
	lein clean
	lein with-profile -user,-dev install
	lein with-profile -user,-dev,+mranderson-plugin install

-.inline: install
+.inline: bootstrap-install
	rm target/*.jar
	rm pom.xml
	lein with-profile -user,-dev,+mranderson-plugin inline-deps :skip-javaclass-repackage true
	touch .inline

inline: .inline

test:
	lein test

integration-test:
	.circleci/integration_test.sh

+install: .inline
+	lein with-profile -user,-dev,+mranderson-profile install
+
deploy: .inline
	lein with-profile -user,-dev,+mranderson-profile deploy clojars

clean:
	lein clean
	rm -rf .inline

This seemed to work, but if it does not make sense please let me know so I can better understand. If it does make sense I can include the change in the PR.

Next Steps

If adding some brief developer docs is something that interests you too, I'll follow up with a PR.

So the Makefile change seems to make sense. The tweak allows me to easily test locally with MrAnderson with its own deps inlined. Which is handy for things like cljdoc previewing.
