// SYNOPSIS
//
file_info::file_info(
char const *path_name, int dir_index, size_t file_size,
char const *title, int num_words

//
// DESCRIPTION
//
// Construct a file_info. If a title is given, use it; otherwise set the
// title to be (just) the file name (not the path name).
//
// Additionally record its address in a list so the entire list can be
// iterated over later in the order encountered. The first time through,
// reserve files_reserve slots for files. If exceeded, the vector will
// automatically grow, but with a slight performance penalty.
//
// PARAMETERS
//
// path_name The full path name of the file.
//
// dir_index The numerical index of the directory.
//
// file_size The size of the file in bytes.
//
// title The title of the file only if not null.
//
// num_words The number of words in the file.
//
//*****************************************************************************
