Detailed Description

Class dealing with arrays of points used in cutting/segmentation.

'Code to find the optimum fixed pitch segmentation of some blobs.'

Hypothesis is that, if we step back, this 'looks' like a crack in the surface of a frozen lake, where a FPCUTPT is a subsequent point from which the crack progresses to next point. Tesseract cracks the blobs this way, looking for something that statistically satisfies a bunch of constraints.

Can be just a point, ex: end of best path, or an array of point, ex: cutpts.

FIX: How are cuts related to segments? Are they co-existing? The FPSEGPT::FPSEGPT //constructor seems to suggest this, 'Constructor to make a new FPSEGPT. The existing FPCUTPT is duplicated.'

Hypothesis is that while cut points are relative to a starting point and an ending point, ie successive points are relatively oriented, segments specify both starting and ending points. I'm confused.

Also, sometimes a cut is made but marked as 'faked', probably just to determine whether it improved the rating. If it did, it's marked as non-fake, otherwise it's abandoned.
