+class TImMessageField
+/** Parses email message header fields for valid Internet email addresses, 
+comments and aliases.
+
+A comment is a string surrounded by parentheses, as defined in RFC822, 3.1.4. 
+
+An alias is defined as any substring which appears to the left of a legal email address:  
+for example, the string "this is an alias" in "this is an alias <an.email@address.com>".  
+
+For email addresses, the string being parsed: 
+1) must contain an @ character, surrounded by valid address characters; 
+2) may not contain more than one address or @ character; 
+3) may contain aliases and comments.
+
+Note the following about the implementation of this class:
+
+1. Functions that test subject lines, ValidSubjectLine(),  and alias names, ValidAliasName(), were 
+initially written to test that the strings did not contain characters outside a limited 
+ASCII range. Unicode characters are now allowed, so these functions now always return true.
+
+2. Of the four overloads of GetValidInternetEmailAddressFromString(), only the first has a meaningful
+implementation.
