Classes
class	CrdBidOffs
	Just hold inl, crl, x, y and offs. For 2D, crl=nr. More...
class	CubeData
	Position info for an entire 3D cube. The LineData's are not sorted. More...
class	CubeDataFiller
	Fills CubeData object. Requires inline- and crossline-sorting. More...
class	CubeDataIndex
	CubeData index for fast trace number <-> BinID lookups. More...
class	CubeDataIterator
	Iterates through CubeData. More...
class	CubeDataPos
	Position in a CubeData. More...
class	Detector
	Determines many geometry parameters from a series of Coords with corresponding BinID or trace numbers and offsets if prestack. More...
class	Line2DData
	Position info for a 2D line. More...
class	Line2DDataIterator
	Iterates through Line2DData. More...
class	Line2DKey

class	Line2DPos
	One position on a 2D line. More...
class	Line2DPos3D
	Line2DPos with a z value. More...
class	LineData
	Position info for a line - in a 3D cube, that would be an inline. Stored as (crossline-)number segments. More...
class	LineSet2DData
	Position info for a set of 2D lines. More...

Detailed Description

Position info, often segmented.

In data cubes with gaps and other irregulaities, a complete description of the positions present can be done by describing the regular segments per inline. No sorting of inlines is required.

The crossline segments are assumed to be sorted, i.e.: [1-3,1] [5-9,2] : OK [9-5,-1] [3-1,-1] : OK [5-9,2] [1-3,1] : Not OK

Note that the LineData class is also interesting for 2D lines with trace numbers.
