CemrgCommonTools View: add a "Reorient/Resample" button

[alonsoJASL]

For an upcoming release of CemrgApp, this would be really helpful. Sometimes users can't convert their DICOMS, even with the alternative DICOM reader. Even though one can point them to tools like https://github.com/rordenlab/dcm2niix , the DICOMs are not resampled to be isotropic and they are not reoriented to RAI. This could cause problems with some of our views.

I guess rather than assigning a button, this should be handled behind the scenes, when conversion is happening.

[alonsoJASL]

There are cases where neither the default DICOM reader nor the alternative one work for converting. The problem there is that if someone uses an external DICOM reader (e.g. Matlab or something else) they don't have a chance to resample it to isotropic (or realign it to RAI).

I think this might be feature only a handful of users would use/need, the more knowledgeable ones. So I might be trying to fix a problem not a lot of people have. Happy to discuss further, otherwise, we can scrap this.

Consider having a separate plugin for common image processing tools (similar to the QmitkCemrgCommonTools).

Examples:

• Cropping
• Reorient to RAI (or anything you want)
• ...
