Returns current column within a string, counting newlines as line separators.
The first column is number 1.
Note: the default parsing behavior is to expand tabs in the input string
before starting the parsing process. See
:class:`ParserElement.parseString` for more
information on parsing strings containing ``<TAB>`` s, and suggested
methods to maintain a consistent view of the parsed string, the parse
location, and line and column positions within the parsed string.

A memoizing mapping that retains `capacity` deleted items
The memo tracks retained items by their access order; once `capacity` items
are retained, the least recently used item is discarded.
