// The following information is available from an Iterator:
//
// * index - repetition number, starting from zero.
// * number - repetition number, starting from one.
// * even - true for even-indexed repetitions (0, 2, 4, ...).
// * odd - true for odd-indexed repetitions (1, 3, 5, ...).
// * start - true for the starting repetition (index 0).
// * end - true for the ending, or final, repetition.
// * length - length of the sequence, which will be the total number of repetitions.
//
// * letter - count reps with lower-case letters: "a" - "z", "aa" - "az", "ba" - "bz", ..., "za" - "zz", "aaa" - "aaz", and so forth.
// * Letter - upper-case version of letter.
// * roman - count reps with lower-case roman numerals: "i", "ii", "iii", "iv", "v", "vi" ...
// * Roman - upper-case version of roman numerals.
///
// * first - true for the first item in a group - see note below
// * lasst - true for the last item in a group - see note below
//
// Note: first and last are intended for use with sorted sequences. They try to
// divide the sequence into group of items with the same value. If you provide
// a path, then the value obtained by following that path from a sequence item
// is used for grouping, otherwise the value of the item is used. You can
// provide the path by appending it to the path from the repeat variable,
// as in "repeat/item/first/color".
//
// PHPTAL: index, number, even, etc... will be stored in the
// $ctx->repeat->'item' object. Thus $ctx->repeat->item->odd
