treatment: Binary treatment column name.
covariates: Character vector of continuous covariates.
n_neighbors: Number of matches per treated unit.
caliper: Maximum Mahalanobis distance for a valid match.
replace: If TRUE, controls may be re-used.
exact: Optional character vector of variables to match exactly prior to distance matching.

Value
