Fix warping #232

Fixed warping of ROI and probability map from template space into native space. In
def prepare_map()
replaced
self.mapping = reg.read_mapping(mapping, self.img, reg_template, prealign=reg_prealign)
with
self.mapping = reg.read_mapping(mapping, self.img, reg_template, prealign=np.linalg.inv(reg_prealign))
replaced the pre_align with its inverse _aNNe
that fixed the warped rois and the warped prob maps which had been warped wrongly

Hello @Anneef! Thanks for opening this PR. We checked the lines you've touched for PEP 8 issues, and found:

Hi,
this fix corrects the warping of ROI and probability maps in segmentation.py. It had been done with using the forward direction of the warp operation used to warp native on template. Now it is done with the inverse, resulting in ROI and probmap, which were previously registered to template, being warped into native space.
Also, added debugging lines, which are currently commented-out, in preparation for an optional debugging feature mode that allows step by step tracking of problems with image registration.
