Functions in spm12 hides native functions in spm

[nbeliy]

The functions in hMRI-toolbox/spm12 folder are added to matlab by default.
All of them except spm_dicom_dict effectively hides corresponding function in spm12.

This is a dangerous situation and those functions must be either moved to it own namespace,
or changed names to hmri_...

Agreed.

These spm12 functions were added at the time because they were not part of the public SPM release yet. Now it would be safer to rely on the SPM distribution, which ensures that the functions are fixed when needed. The small risk is the that some new features breaks back compatibility but this is IMO still less risky.

For the sake of completeness, I would also introduce a SPM version check when hMRI gets initialized. This way we would warn the user that their version of SPM is too old...

If hMRI toolbox is dependent on SPM, then using the SPM version of these functions is preferable, hoping that they do not change interface
