/**
* EmojiInput - augmented inputs for emoji and autocomplete support in inputs
* without having to give up the comfort of <input/> and <textarea/> elements
*
* Intended usage is:
* <emoji-input v-model="something">
* <input v-model="something"/>
* </emoji-input>
*
* Works only with <input> and <textarea>. Intended to use with only one nested
* input. It will find first input or textarea and work with that, multiple
* nested children not tested. You HAVE TO duplicate v-model for both
* <emoji-input> and <input>/<textarea> otherwise it will not work.
*
* Be prepared for CSS troubles though because it still wraps component in a div
* while TRYING to make it look like nothing happened, but it could break stuff.

* Suggestion is an object containing following properties:
* displayText: string. Main display text, what actual suggestion
* represents (user's screen name/emoji shortcode)
* replacement: string. Text that should replace the textAtCaret
* detailText: string, optional. Subtitle text, providing additional info
* if present (user's nickname)
* imageUrl: string, optional. Image to display alongside with suggestion,
* currently if no image is provided, replacement will be used (for
* unicode emojis)
*
* TODO: make it asynchronous when adding proper server-provided user
* suggestions
*
* For commonly used suggestors (emoji, users, both) use suggestor.js
