+/** 
+ * @file llsearcheditor.h
+ * @brief Text editor widget that represents a search operation

+ *		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)
