Summary: Enhancements to TimeSeries class
Initial Comment:
I propose the following changes to TimeSeries class:
-- to add an extra template parameter Time with default to Date - this will allow for use of alternative data/time types (e.g. time_t);
-- to add time and value projection iterators so that one would be able to iterate through time and values independently - this feature would allow for treatment of a TimeSeries object as a simple sequence of time and/or value elemnets;
-- to add time and value iterator generating members: begin_time(), end_time(), begin_values(), end_values()
The diff of proposed changes is attached

Message:
Slava,
unfortunately, redefining TimeSeries as
template <class T, class Time = Date, class Container = std::map<Time, T>
>
is not backward-compatible with the existing declaration; existing client
code instantiating TimeSeries<T, MyContainer> would break. As Time needs to
come before Container in the template parameters, I don't think we'll be
able to apply this change until we start breaking things for a 2.0
release.
However, the iterators you defined would be a welcome addition. May you
attach a new diff that adds them, but without the Time template parameter?
Thanks,
Luigi
