/**
* @file llsearcheditor.h
* @brief Text editor widget that represents a search operation
*
* Features:
* Text entry of a single line (text, delete, left and right arrow, insert, return).
* Callbacks either on every keystroke or just on the return key.
* Focus (allow multiple text entry widgets)
* Clipboard (cut, copy, and paste)
* Horizontal scrolling to allow strings longer than widget size allows
* Pre-validation (limit which keys can be used)
* Optional line history so previous entries can be recalled by CTRL UP/DOWN
