/** \class RegularExpressionSeriesFileNames
* \brief Generate an ordered sequence of filenames that match a
* regular expression.
*
* This class generates an ordered sequence of files whose filenames
* match a regular expression. The file names are sorted using a sub
* expression match selected by SubMatch. Regular expressions are a
* powerful, compact mechanism for parsing strings.
* Expressions consist of the following metacharacters:
*
* ^ Matches at beginning of a line
*
* $ Matches at end of a line
*
* . Matches any single character
*
* [ ] Matches any character(s) inside the brackets
*
* [^ ] Matches any character(s) not inside the brackets
*
* - Matches any character in range on either side of a dash
*
* * Matches preceding pattern zero or more times
*
* + Matches preceding pattern one or more times
*
* ? Matches preceding pattern zero or once only
*
* () Saves a matched expression and uses it in a later match
*
* Note that more than one of these metacharacters can be used
* in a single regular expression in order to create complex
* search patterns. For example, the pattern [^ab1-9] says to
* match any character sequence that does not begin with the
* characters "ab" followed by numbers in the series one
* through nine.
