Changes in version 0.0.2 (2024-02-08)                  

  - Changed the var argument in plot(., type = "extrapolation") to
    variables (var still works as an abbreviation).

  - Added a unit testing framework.

  - Weights now have an average of 1 in each treatment group. This only
    affects the display of the weights, making it easier to assess
    extreme weights, but does not affect balance or any other property
    of the weights.

  - When using cluster-robust standard errors in lmw_est(), the degrees
    of freedom for the corresponding t-testing as now computed as one
    less than the number of clusters to be consistent with other
    software.

  - "IPWRA" is now an acceptable alias for "WLS" when supplied to the
    dr.method of lmw() with base weights. IPWRA is the name Stata gives
    to the same estimator.

  - When a weightit or matchit object is supplied to obj in lmw() or
    lmw_iv(), the focal component of the supplied object is
    automatically supplied and does not need to be specified. A warning
    will be thrown if focal is supplied and differs from the focal
    component of the supplied object.

  - Errors are prettier.

                 Changes in version 0.0.1 (2023-03-14)                  

  - First version!
