intersect_averagers: Find common averaging "locations"
In dshemetov/evalcast-mirror: Tools For Evaluating COVID Forecasters

Description Usage Arguments Details Value

Many scoring or plotting functions compute averages over "locations" for a number of different grouping facets. We say "locations" because this most often the geo_value that gets averaged over, while the groupings are the forecaster, forecast horizon, and forecast date. But under other combinations may be desired.

1	intersect_averagers(cards, grp_vars, avg_vars)

`cards`	long data frame
`grp_vars`	character vector of indicating variables to group on
`avg_vars`	character vector of variables to average over

In the case that we want to make comparisons, we want the avg_vars to be common. This function finds common avg_vars. An example would be if one forecaster makes predictions for a location that others don't, we would want to throw it when ever we compute error measures.

a data frame of the same type as input
