`x_mat`	Input/design matrix
`cov_x`	The covariance of `x_mat`. Can be rank_adjusted by using `covariance_with_ranks`.
`weight_list`	List of weight vectors. See 'generate_random_weights' to automatically generate a reasonable set of vectors.
`treat_vec`	Logical (or 1/0) vector, indicating treatment (or control).
`match_method`	"with_replacement", "optimal", or "greedy"
`n_sinks`	Number of potential matches that don't need to be matched.
`caliper_list`	Forces matches that are close on some metric.
`propensity_list`	Default NULL. List of propensity scores.
`sqrt_mahal`	Whether to use square root of Mahalanobis distances.
`tol_val`	For optimal matches, you can set a tolerance to be within optimality of, which can be zero for perfect optimality.
