Fix URLs in README, convert to roxygenv0.2.3

- The roxygen conversion was done using Rd2roxygen - Also edit _pkgdown.yml to group the reference - Use markdown bullet lists for lod and loq docs

+therefore, <code>calplot</code> does not draw prediction bands for such models.</p>
+<p>It is possible to compare the <code>calplot</code> prediction bands with
+the <code><a href="lod.html">lod</a></code> values if the <code><a href="lod.html">lod()</a></code> alpha and beta parameters
