'Requires:
my_string --the string to parse.
type -- the type of string.
Returns:
Returns a string for a field instrution attribute.
Logic:
This handles all "large" fields, which means everything except
toc entries, index entries, and bookmarks
Split the string by spaces, and get the first item in the
resulting list. This item is the field\'s type. Check for the
action in the field instructions dictionary for further parsing.
If no action is found, print out an error message.'
