(math/R-zoo) Updated 1.8.9 to 1.8.10

Changes in Version 1.8-10

  o The transform() method now internally uses a list of zoo series (as opposed
    to a data.frame of numeric variables, as used in previous versions). This
    means that the transformations can really operate on full zoo series.

  o Added MATCH() methods for classes "Date", "POSIXct", and \ 
"POSIXlt", all
    of which essentially match the underlying numeric vector (suggested by
    Kurt Hornik).

  o In zooreg() the "ts.eps" argument is now also used (in squares) as the
    tolerance in the all.equal() comparisons used to determine the underlying
    regular time grid.
