Chest Wall segmentation:
While cropping the section of the chest to process User is aiding the segmentation at the same time.
Instead of drawing the box User chooses a line segment that specifies the cropping area.  In addition User asked that the segment starts and ends on the Chest Wall boundary as close as possible.
This would help tremendously with the Initial Seed during the MapFit procedure.



Corrected a bug in integrated Chest Wall segmentation function, when AirMask was produced as always empty, thus providing no constraints to the procedure.

Whole Breast segmentation using MapFit:  while EdgeWave seems to be promising on some examples, there are numerous extra challenging situations were EdgeWave would not work
out by itself.

Some trials of algorithms for making an initial Chest Wall contour on the Mid-Sagittal slice.
A manual rectangular seed placed and EdgeWave ran with parameters   SiLo\SiHi = {0.5,2}  Peel\Grow = {5,10}mm

Chest wall\Whole Breast segmentation:  implemented a specialized dialog to cover both.

MapFit\Breast segmentation
Implemented a dual-smoothness concept:

a) Deformation field is smooth so there is a separate smoothing procedure for that
with the constant organ-independent parameters (no UI-parameters).

b) Organ boundary smoothness:  this is the constrained and is smoothed separately.  User sets the parameters defining the smoothness of the resulting organ contour.

Trying to figure out why resulting contour does not follow intuitive edges and shortcuts the sides.

MapFit Multiagent architecture:  Implemented 2 additional algorithms of primitive candidates integration based on SoftMax scoring conversion.

Added a specialized menu item under   Applications>Breast FGT> Segment Chest Wall with MapFit
Implemented an improved released version of the 99% automatic Chest Wall segmentation from the Axial Plane.

Implemented a new modification of the MapFit AG (Multi-Agent) method.
It comes with much simplified parameter set:

Default parameters on FireVoxel UI would be set to correctly process the Chest Wall 12-case batch.

Segmentation by Contour Evolution (MapFit):  released the 1st version and processed the ISMRM test set of 12 cases.

EdgeWave crash defect: in provided example the Seed Z coordinate was outside the image bounds.  Provided a corresponding error message and the exit.
Fixed the defect presented as unexpected change of slice in MagTrace.  This was related to some coordinate calculation code on some specific resolution\dimension combinations.

Some test cases for Chest Wall problem have a major discontinuity of the Chest Wall shape.
Just changing the Slice # by 4,  the shape is changing by dozens of voxels, especially see on the left.

Fixed defect in SimpleEdge procedure when the last slice was not producing result resulting in empty map for single slice volumes.
