[NTG-context] math font fallback for palatino \cal

Dear gang, Using pagella (palatino) for a project here. Unfortunately texgyrepagella-math.otf has a rather unattractive set of \cal caps; schola, termes, bonum etc. all use the same and much better-looking set. So I decided to try and define a palatino math set with the \cal caps from schola (= termes etc.). Succeeded after some trial and error: attached are the positive results. Others may find the experiment useful or even worth wikifying; it's a nice fallback exercise. Maybe there is a better or more up-to-date way to do this: In any case, feel free to critique the attached.
