[pomadchin]

Update SBT up to 1.0v after its release (current version is 1.0.0-M5), it compiles Scala using Zinc and should significantly reduce compilation times.

// to compare, using the current sbt compile time is 215s+ of the same thing on my laptop; not too bad

There are still problems with old sbt plugins support (as sbt 1.0.0+ requires all plugins to have Scala version 12.0+).

To track down update see this branch (not supported plugins were commented out).

SBT 1.0 Branch works, only dep graph plugin still doesn't support SBT 1.0 but it will be released soon.

[pomadchin]

Dep graph plugin of version 0.8.3-SNAPSHOT is released, but contains come bugs. I'm tracking this, to create an SBT 1.0 PR.

They should just roll the dep graph plugin right into the main code base.

Also, GeoTrellis has some custom code somewhere that alters our SBT prompt. SBT 1.0 has this behaviour built-in (e.g. it displays what subproject you're in), so we can remove our custom code.
