Message:

Fixes for Export data wavelength user input. Had out of order bug and logic, which was askign for wavelength when not needed. SHould be more logical now.

 3. Keep the ipf file in that experiment, if needed minimize or hide, do NOT kill
 4. Follow these instructions below to setup that specific Form factor

+### Core-Shell-Shell-Shell-sphere, January 2022
+This is modified version of NIST f3Shell, created by Jan Ilavsky in January 2022. Original author is Steven Kline from NIST. 
+
+USE in Irena :
+* In Modeling II select User form factor 
+* In panel put in "Name of Form Factor function this string:    FF_CoreThreeShell
+* In Panel put in Name of volume FF function this string:     FF_CoreThreeShellVolume
+* Read the code at the top, this is complicated. 
+* There are too many parameters for Irena GUI, some must be set as constants and cannot be fitted. Changing requires code modification. 
+* SLD values are implicitely multipled by 10^10cm^-2, so insert only a number. These are rhos not, delta-rho-square
+
+**In main panel set contrast = 1 !!!!! Contrasts are part of the form factor in this case.**
