augment.breathtestfit

Broom method <code><a href="https://generics.r-lib.org/reference/augment.html">augment</a></code> to compute predicted values 
from the results of class <code>breathttestfit</code> as generated by 
<code>nls_fit</code> or <code>nlme_fit</code>.

Reads several formats of 13C data (IRIS/Wagner,
BreathID) and CSV.  Creates artificial sample data for testing.  Fits
Maes/Ghoos, Bluck-Coward self-correcting formula using 'nls', 'nlme'.
Methods to fit breath test curves with Bayesian Stan methods are
refactored to package 'breathteststan'. For a Shiny GUI, see package
'dmenne/breathtestshiny' on github.
