[chuck] time signature durations

[Michael Heuer]

Hello,

Is there built-in support for time signatures, or should I just be doing
something like

400::ms => dur q;
4::q => dur w;

2::w => now;
while (true)
{
  q => now;
  ...
}

It would be nice to be able to write a file or shred using time-signature
based durations and be able to change the values of those durations from
somewhere else, effectively changing the BPM of everything you may have
running simultaneously.
