EDD from CRL js script

On or about Sept 21 2023 the BC MFMs switched the reference for dating pregnancies using CRL from the Lessoway reference to the Robinson reference. This means that for those using the Pregnancy Calculator that converts a CRL into weeks and days - that part of the calculator was often off by 1 day ( often less by 1 day). I have updated the JS script that is stored in the image library that does this work, so that it now uses the Robinson method. If you wish to update this on your system, you will need to go into your image files and delete a file called EDDfromCRL.js and replace it with the new one.
