Template::Plugin::Datafile - Plugin to construct records from a simple data file

       Andy Wardley <abw@wardley.org> <http://wardley.org/>

       Should handle file names relative to "INCLUDE_PATH".  Doesn't permit use of '":"' in a field.  Some
       escaping mechanism is required.

       This plugin provides a simple facility to construct a list of hash references, each of which represents a
       data record of known structure, from a data file.

           [% USE datafile(filename) %]

       A absolute filename must be specified (for this initial implementation at least - in a future version it
       might also use the "INCLUDE_PATH").  An optional "delim" parameter may also be provided to specify an
       alternate delimiter character.

           [% USE userlist = datafile('/path/to/file/users')     %]
           [% USE things   = datafile('items', delim = '|') %]

       The format of the file is intentionally simple.  The first line defines the field names, delimited by
       colons with optional surrounding whitespace.  Subsequent lines then defines records containing data
       items, also delimited by colons.  e.g.

           id : name : email : tel
           abw : Andy Wardley : abw@tt2.org : 555-1234
           sam : Simon Matthews : sam@tt2.org : 555-9876

       Each line is read, split into composite fields, and then used to initialise a hash array containing the
       field names as relevant keys.  The plugin returns a blessed list reference containing the hash references
       in the order as defined in the file.

           [% FOREACH user = userlist %]
              [% user.id %]: [% user.name %]
           [% END %]

       The first line of the file must contain the field definitions.  After the first line, blank lines will be
       ignored, along with comment line which start with a '"#"'.
