I've a use case that I'm trying to solve. I have Name column which is unstructured in the sense that some names have an initial for middle , some have full name and some don;t have middle name at all. I've created 2 new fields First Name and Last Name. And for an example QUENTIN W WORTHY should have last Name of Worthy and First Name of Quentin M. Similarly MATTHEW TAYLOR RODRIGUEZ should have last name of Rodriguez and First Name of Matthew Taylor
