More General Utilities With Representation Of Time In `idata` Objects #34

TODO: Collect notes on time and idata objects.

This functionality should

  1. Allow for multiple variables to have their coordinates replaced with different dates at the same time.
  2. The new coordinates should be derived by the user providing a start date and a time step.
  3. If seems reasonable to you, I think we should only have to specify a dimension name. Then that dimension should have its coordinates changed in all groups where it exists.

@damonbayer Ex ante, these three points seems reasonable to me.

From elsewhere:

I've been thinking about this:

Allow for multiple variables to have their coordinates replaced with different dates at the same time.

Multiple variables = "multiple idata groups"?

and "different dates" is different start_date_isos or intervals 1, 7, 14, etc...? Both should be supported, correct?

You could have some weekly Rt thing that starts on January 1 and a daily hospital admissions that start on February 1. You should be able to specify that.
