🦄 Mongoose dedupe

Like uniqueness checking but on steroids. Check for individually unique fields, collectively unique queries and unique subdocument values all from within the mongoose Schema.

For Parents

Prop	Description
dedupe	Use this to lookup a single field value's uniqueness
dedupeWith	Runs all properties with this flag in a query

For Subs

Prop	Description
distinct	Use this to make a sub-document value unique. If merge or accumulate options are not present in sibling options, then it will error on match.
merge	Use this to overwrite a sub-document property on match
accumulate	Use this to add to a sub-document property on match

Additionally, you can pass an "options" property to the plugin to append query data to each lookup. This is useful if you're using another plugin, such as one that checks the "active" state of a document.
