recent_group(outcomes, metadata, t_past, trt_unit = 1, by = 0.1,
  maxep = 1, cols = list(unit = "unit", time = "time", outcome = "outcome",
  treated = "treated"))

`outcomes`	Tidy dataframe with the outcomes and meta data
`metadata`	Dataframe of metadata
`t_past`	Number of recent time periods to balance especially
`trt_unit`	Unit that is treated (target for regression), default: 0
`by`	Step size for tolerances to dry, default: 0.1 * magnitude
`maxep`	Maximum tolerance to consider
`cols`	Column names corresponding to the units, time variable, outcome, and treated indicator
