Implement Common (reference) space resampling

[gdevenyi]

Need to be able to automatically generate transforms to a reference space if provided and produce DBM outputs in that space.

Q: does it happen in model and dbm, or just dbm?

[gdevenyi]

This should go in the DBM part, since the base modelbuilding code should be strictly limited to just modelbuilding.

[gdevenyi]

I now think this should go in the modelbuilding section because this may be needed by users to move subject-level measures to common space.

[gdevenyi]

Should we include some kind of handling of label files if provided?

Edit: maybe a seperate label propagation script.

[gdevenyi]

Resample input subjects into template space.

• label files
• metrics
• modulate by jacobian (needs DBM outputs)
• images themselves (needed for QC)
