* Improved support for testing custom schemas using a MockNetwork.
* Removed `requiredSchemas` from CordaPluginREgistry configuration
Custom schema registration now uses classpath scanning (CorDapps) and explicit registration (tests) following same mechanisms as flow registration.
* Updated following PR review feedback.
* Helper function to return Kotlin object instance fixed and moved to core InternalUtils class.
* Fixed auto-scanning Unit test to assert correct registration of custom schema.
* cleanup comment.
* Changes following rebase from master.

Remove unnecessary QueryEditor implementation from NodeVaultService.
* Updated documentation and changelog.
* Misc fixes to broken documentation code snippets.

* Performance optimisation: only return totalStatesAvailable count on Pagination specification.
* Changed DEFAULT_PAGE_NUMBER to 1 (eg. page numbering starts from 1)
* Changed MAX_PAGE_SIZE to Int.MAX_VALUE

* Added optional sorting by aggregate function.
* Added Jvm filename annotation on QueryCriteriaUtils.
* Added documentation (API and RST with code samples).
* Incorporating feedback from MH - improved readability in structuring Java and/or queries.
* Remove redundant import.
* Removed redundant commas.
* Streamlined expression parsing (in doing so, remove the ugly try-catch raised by RP in PR review comments.)
* Added JvmStatic and JvmOverloads to Java DSL; removed duplicate Kotlin DSL functions using default params; changed varargs to lists due to ambiguity
* Fix missing imports after rebase from master.
* Fix errors following rebase from master.
* Updates on expression handling following feedback from RP.
* Fix https://github.com/corda/corda/issues/949 by providing a default StateStatus argument to all QueryCriteria types.
