The function returns 0 if the two names are identical;
returns a negative number if name1 comes before name2
returns a positive number if name2 comes before name1.

  "Comes before" has the usual sense for arranging names in alphabetical order.
  For example, the following list of names are considered to be in order:
  John B. Allan
  John B. Allen
  Susan B. Allen
  Susan C. Allen
  Phu X. Nguyen
  Phil R. Olde
  Adam A. Older

returns 0 if the two strings are equal
returns a negative value if string1 comes before string2
returns a positive value if string2 follows string1.
