* Minor: improve javadocs in NodeInfo
* Minor: use package descriptions in Kotlin build of api docs too, not just javadocs.
* RPC: make RPCConnection non-internal, as it's a core API. Move docs around so they're on public API not internal API.
* Add an IntelliJ scope that covers the currently supported Corda API.
This is useful when used in combination with the "Highlight public
declarations with missing KDoc" inspection.
* Ironic: upgrade the version of the Gradle plugin that checks for upgraded versions of things.
It had broken due being incompatible with the new versions of Gradle
itself.
* Docs: flesh out javadocs on ServiceHub
* Docs: add @suppress to a few things that were polluting the Dokka docs.
* Docs: mention RPC access in NodeInfo javadoc
This improves the Java API and makes it more idiomatic. The methods
were not moved to be static methods of the relevant types in all cases
due to a bad interaction with a Kotlin auto-completion bug, and because
static methods on interfaces are new in Java 8 and Kotlin is not yet
emitting Java 8 bytecode.
Also, introduce a packages.md file so packages can be documented.
Removed redundant parts of the docsite generator.
Gradle now calls the docsite requirements installation script when building docs via buildDocs
Added docs build script and moved all docs building related code into it
Corrected directories for build.
