+Find and return the index of the best matched template field. The method uses a matching algorithm which compares the content type of the template fields with that of the incoming contact item.
+
+Matching Algorithm Steps:
+========================
+
+The algorithm is based on a scoring mechanism counting 'hits' and 'misses' in order to find the best possible field match within the fieldset of the template.
+
+1. Loop through all the contact item fields of the template.
+
+For each template field:
+
+2. Perform a strict, or exact, match between the vCard mappings of the template field and the field to be matched.
+3. If the vCard mappings match exactly, compare User Flags values and amend the overall score accordingly.
+4. Loop through all the field types (TFieldType array) stored as part of the content type of the field to be matched.
+
+For each field type of the field to be matched:
+
+5. Loop through the field types of the iterated template field to find a field type match. Amend the 'hits' and 'misses' count accordingly.
+6. Calculate the overall score weighing the 'hits' and 'misses' count.
+7. Amend the overall score count in order to account for special cases (e.g. user defined fields)
+8. Compare the overall score with the best score. If score > current best score, replace the 'bestScore' count and 'bestMatch' index.
+
+9. Return the 'bestMatch' field index of the template field.
+
+@param aContentType		The content type of the field to find a match for.
+@param aUserFlags		The user flags of the field to find a match for.
+@param aExactMatch		Boolean to indicate an exact field match within the template.
+
+@return The index of the best matched template field, if found, else KErrNotFound.
