additions to plugins/fn-derivatives
Submitted by Tino
Created attachment 227030 contains all modified/added files in plugins/fn-derivatives
I'd like to add a few functions to the plugin, mainly barrier options which are currently missing. All the files I've changed/added are attached. It compiles with the git version but I had to test with 1.10.17 (as I'm having trouble with either gtk3 or cairo and gnumeric causes an X BadValue error and dies). A test sheet is included so if something doesn't work let me know and I'll try to fix it. Let me know what you think.
