Liu Threshold Analyzer 1.0.1

Added

• Open. A saved JSON session can now be read back into the window from the
  footer, which is what the Save option had been promising. A file that is not
  a session, or holds a non-positive measurement, is refused with a message
  rather than half-loaded.

Changed

• The energy axis starts logarithmic. That is the view in which Liu's
  method is a straight line and the one every screenshot shows; a new user no
  longer has to find Settings to see it.

Fixed

• The threshold uncertainty now uses the whole covariance of the fit. The
  slope and intercept of a least-squares line are correlated, and the earlier
  propagation treated them as independent, although the documentation said
  otherwise. A test checks the result against an independent computation of
  the covariance matrix.
