secr 4.3.1, secr app 1.3, openCR 1.4.4

[Murray Efford]

 It's been a busy week. secr 4.3.1 (now on CRAN) has some significant bug fixes and a few new features. The first serious release of secrapp (a Shiny app for running secr) is now live (note also the step-by-step guide). Changes in openCR 1.4.2 and 1.4.4 are minor. The Density web page has been updated: it's time to push the old Windows application Density into the background. Raw input files are provided there for various examples.

The live link lets you run secrapp on a University of Otago machine without installing it yourself. We will see how this works out: peaks in demand may crash it, so for class use etc. you will probably want to run it locally (see GitHub).
