This adds a new setting key called updateOptions, which can enable
consolidated resolution for update task.
The consolidated resolution automatically generates an artificial
module descriptor based on the SHA-1 of all external dependencies.
This consolidates the Ivy resolution of identical Ivy dependency
graph across multiple subprojects.
This is how it's enabled:
updateOptions := updateOptions.value.withConsolidatedResolution(true)
* Added the top-level interface project for communicating across scala versions within a jvm.
* Added plugin project containing analysis compiler plugin
* Added component compiler to build xsbt components against required version of Scala on the fly
* Added interface to compiler that runs in the same version of Scala
* Added frontend that compiles against a given version of Scala with or without analysis.
