/*
* - All get/set functions will return nothing if the key is not found in the database.
* - If you want to delete a key, use hdelAsync. Writing extended functions for deleting keys is pointless.
* - Member key names are formatted as "guildID-userID". Use this.member.del(guildId + '-' + id) to delete member data.
