+/**
+ * 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.
