Using Compromise.js to get name formats right.

determineNameFormat("John Michael Smith");
// Output: First Name Middle Name Last Name format

determineNameFormat("Smith, John Michael");
// Output: Last Name, First Name Middle Name format

determineNameFormat("Smith John Michael");
// Output: Last Name First Name Middle Name format

determineNameFormat("John Michael-Smith");
// Output: First Name Last Name-Last Name format
