   dateString is a date passed as a string in the following
   formats:

   type 1 : 19970529
   type 2 : 970529
   type 3 : 29/05/1997
   type 4 : 29/05/97
   type 5 : 05/29/1997
   type 6 : 05291997
   type 7 : 052997
   
   dateType is a numeric integer from 1 to 7, representing
   the type of dateString passed, as defined above.

   Returns -1 if the date passed is behind todays date
   Returns 0 if the date passed is equal to todays date
   or if dateType is not 1 to 7
   Returns 1 if the date passed is ahead of todays date
