intelligent slice selection

[raamana]

• Show slices highlighting ROIs known to be frequently erroneous
• also, find all ROIs with outlying values (such as 5% zeros, or over 6mm thickness) and show slices on them
• implement keyboard shortcuts to show bring these up as necessary, Alt+E for erroneous ROIs, Alt+O ROIs with outlying values... also ability to show neighbouring slices with arrow keys to help gain confidence on the accuracy of current slice

[raamana]

implementing [some of these] may lead to reduced responsiveness, as it has to read large thickness files and some ROI-wise stats on them for each subject.

Relying aparc.stats might help, but that only provides mean and SD which destroy useful info, such number of 0mm values for thickness etc
