Feature: Analysis shape viewer should be able to show individual subjects

[JakeWags]

This should behave similarly to Studio to maintain parity

[JakeWags]

This should look like the Samples tab in Studio:

Notable features:
options -

• All Samples: renders all reconstructed samples in the dataset with particles. Should look and behave similarly to the standard shapeviewer.

• Single Sample (with number field for sample #): Show single selected subject with particles.

  • Median: shows the median subject

• Show difference to mean: shows the difference to mean. When All Samples is selected, shows a uniform scale. When Single Sample is selected, scale changes depending on the subject shown

Questions:

• How is median sample calculated? Is this simply the median subject number?
• How are the scales for the mean difference calculated?

How is median sample calculated? Is this simply the median subject number?

The median sample is the sample in the shape model with the smallest total particle to particle difference. It's computed by taking each shape and for each shape, for each particle, adding up the particle to particle distance.

How are the scales for the mean difference calculated?

Usually just the min and max. There are some cases in studio where it auto adjusts as you go through the data though, meaning the min is the min of all values seen so far and max likewise.
