Prepare for 2.8 release

[zachcp]

• add a Makefile for creating unbundled CDK jar files
• use sed to remove large, unused JARs
• manually add Google guava which is a hidden dep in rCDK code (used in several locations so removing might cause breaks)
• bumpversion
• ref Get the bundled JAR size under control cdk/cdk#911
• ref a minimized set of JARs for rCDK cdk/cdk#915 (comment)
• size ~27Mb (similar to previous)

Ah I would do this with a little maven stub project :). But sure sed works as well

[rajarshi]

Probably worth seeing if we can get rid of the Guava dep. - it was mainly for convenience

[johnmay]

I got rid of Guava in CDK in 2.7 I think, do you use this independently?

[zachcp]

When I took Guava out of rcdklibs, the rcdk tests failed. Its at least used here. @rajarshi if you refactor that in the 2.8 branch of rcdk, I can update the libs to remove guava.

[johnmay]

The mulitmap is easy to replace, since 1.8: map.computeIfAbsent(key, k -> new ArrayList<>());

[zachcp]

thanks, John. I modified that file based on your suggestion (PR here; eyeballs welcome) and removed Guava here. If things look good to you both I can move forward with submitting a new release of both packages.

[zachcp]

@rajarshi can you squash merge this (or give me write access)

[rajarshi]

Just merged it. Also happy to give you write access - where do I set that?

[zachcp]

You can set permission levels for individuals or groups within GitHub Settings.

[rajarshi]

OK, you're an admin now, so i think that gives yiou write access to everything
