Set Proper Name Case Function
This script is basic in terms of how much it can handle. It sets the proper case in a "full name" field (i.e. First, Middle and Last names all in one column such as 'BILL MCDOUGLE' or 'terry smith-wenderling'. The function will take any case and set it appropriately including last names with the 'Mc' prefix.
There are some limitations.
1) It can't handle middle names if there is a last name prefix of 'Mc' such as 'McDougle'.
2) I haven't spent any additional time with other last name prefixes such as 'O' in "O'Brien" or 'Di' in 'DiNatale'
3) It is unable to handle bad data such as hyphens at the end of the string with only a single name.
