Mar 30 2020; Update 1.13

The Windows and Linux download files are now much small because I have excluded the MKL libries that I was not using. Now all systems are less than 10 Mbyte. The Mac version is now as a .pkg file which should be easier to install. But if there are any issues, please let me know.

Update VPREDICT K and M functions
Added !NOTRIM qualifier to pedigree line
Fix bug processing model in str() function
