/**
 * Try to mark up CopySpec

@Category(CopySpec)
/**
 * CopySpec will nest in into(CopySpec spec, ) blocks, and Gradle will instantiate DefaultCopySpec itself, we have no ability to inject
 * our own. When appending another copy spec to the task, it'll be created a WrapperCopySpec. In 1.8, there's a slight
 * possibility that we override addChild so we can provide our own instances, or we mod the instantiator.
 *
 * Support some additional properties on CopySpecs. Using CopySpecInternal since its the parent of both DefaultCopySpec
 * and RelativizedCopySpec. The old way used the metaClass on the Class, which effected all CopySpecs in the build. This
 * limits the scope to just without our from/into/rename methods. This style also gives us type safety.
 *
 * It's implemented so that either format of setting is supported, e.g. the Gradle "name value" form or the typical
 * assignment form "name = value".
