  - Add projection-invariant and example-state regression tests.
  - No changes to the numerical projection algorithm or exported API.

                        Changes in version 0.1.0                        

  - Initial CRAN-preparation release.
  - Added lambda-controlled projection correction for cross-domain
    feature adjustment.
  - Added support for two, three, four, or more domains.
  - Added user-selectable projection anchors: "domain_mean",
    "sample_mean", or a custom named vector.
  - Added examples for lambda-dependent PCA overlap, two-domain
    new-sample correction, and three-domain new-sample correction.
