Issue: Flesch-Kincaid Readability Block

VaultWiki 4 performs the Flesch-Kincaid Readability Test against articles to help editors get a sense of how their articles can be improved, and readers a sense of how challenging the read will be. Many wikis have readers of all ages, educational backgrounds, and other first languages looking for their information. This test can help editors make sure that an optimal score is achieved for their desired audience.

Currently the output is posted to the wiki sidebar on the relevant article, and the data is cached after the first time to improve response times. 4.0.0 Alpha 1 only contains support for English-based languages, but we do have plans to add support for other languages incrementally with each release (1-2 languages across VaultWiki in general).

Marking this as Implemented.
