Creating fractional intensity and fractional contribution images from A images

The A (amplitude values) are not that helpful for lifetime users. It would very helpful to instead give an option to create fractional intensity images and fractional contribution images (only for biexp fits).

For biexp. fracIntensity1 = A1/(A1+A2); fracIntensity2 = A2/(A1+A2);

fracContrib1 = (A1*Tau1) / (A1*Tau1 + A2*Tau2) fracContrib2 = (A2*Tau2) / (A1*Tau1 + A2*Tau2)

When doing bi- and tri-exponential fits, the "Fitted Images" drop down in the "Fit" tab of the UI panel has options for showing "f" fractional contribution and "F" fractional intensity images.

(Note that the current selection of combinations of available fitted images could be expanded. For bi-exponential its "A T Z X2"/"A T X2"/"A T"/"T X2"/"T"/"X2"/"F"/"f". Other combinations such as "T F" could be added. I went with a drop down list of canned combinations rather than a list of checkboxes for each kind of fitted image. Of course this latter approach would be more flexible in offering any possible combination. The drop down list is more concise and doesn't jump around as much when you switch from mono- to bi- to tri-exponential. I figured there would be common combinations that people would use.)
