+Usage:
+    from num2word_EN import n2w, to_card, to_ord, to_ordnum
+    to_card(1234567890)
+    n2w.is_title = True

+    to_year(1976)
+    to_currency(dollars*100 + cents, longval=False)
+    to_currency((dollars, cents))
+    
+
+History:
+    1.2: to_ordinal_num() made shorter and simpler (but slower)
+         strings in merge() now interpolated
+         to_year() and to_currency() added
+         
+    1.1: to_ordinal_num() fixed for 11,12,13
