Tidy a(n) zoo object
Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies across models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

A tibble::tibble() with columns:
index |
Index (i.e. date or time) for a 'ts' or 'zoo' object. |
series |
Name of the series (present only for multivariate time series). |
value |
The value/estimate of the component. Results from data reshaping. |
