Downloading and installing SBT

------------------------------

SBT, short for 'Simple Build Tool' is an excellent build system written in Scala. It uses Scala to write the build scripts which gives you a lot of power. It has a plugin architecture with many plugins available, something that we will take advantage of soon. SBT is the preferred way of building software in Scala. If you want to use SBT for this tutorial then follow the following instructions, if not you can skip this section and the next.
