+# This function parses a line from a CSV file (you pass the line as the 
+# argument) into elements in an array.  The CSV elements must be enclosed
+# in double-quotes and then separated by a comma.
+#
+# Commas are replaced by tildes as the separator character in an attempt to
+# allow elements to contain commas.  If elements also contain tildes, a new
+# separation character can be substituted by setting the variable
+# UNIQUE_SEPARATOR to the value of that new separator character.
+#
+# Right now double-quote characters are also removed from the final output,
+# so if one of you elements contains double-quotes this function will remove
+# those double-quotes from within your element.
