Update this with sbt?

首先，将当前的 Java sample 与 issue 中链接的 NetLogo-Extension-Plugin 和 Web-Extension 示例进行比较。定义一个最小的 sbt 设置，并提供仅使用 netlogo.jar 进行构建的分步说明；当新手能够按照这些说明构建 sample extension 时，这项工作就完成了。

Since this is THE sample extension that we encourage people to base their own extensions on, could we update it to include a barebones sbt with step-by-step instructions on how to get it to work with no other .jars than netlogo.jar?

Currently (as far as I understand) we have this to show the java code; the NetLogo-extension-plugin to show sbt, which in turn links to the Web extension to show how to use the sbt.plugins.

It really doesn't make it easy for people who are not used to working with Scala/Typesafe tools, and it has definitely kept me from sharing code here, because takes me half a day (or more) every time I want to. Case in point the Reflection-extension which just published here, and which I am trying to get to work with sbt.

I might not be asking the right question or requesting the right things, or I might be misunderstanding how we're intending to help people contribute NetLogo extensions here. But at the risk of sounding like an ass, I do honestly feel like we should make it easy(ish) for people at my skill level to contribute extensions, and currently it's not.
