Defines lower and upper valid indices.
Is part of the basic characteristic of each Data instance. Encapsulates a start and end index. Size and Dimension are directly extracted from Extent.

| Extent | ( | ) |
default constructor
initialize with Size
The extent will go from -(size-1)/2 to (size-1)/2 for odd sizes, and from -(size/2-1) to size/2 for even images
not explicit on purpose, facilitates easier creation code
| bool Contains | ( | const Extent & | e | ) | const |
Returns true if the given exten is within extent.
| bool Contains | ( | const Point & | p | ) | const |
Returns true if the given point is within extent.
| Point GetCenter | ( | ) | const |
return center
| int GetDepth | ( | ) | const |
| int GetDim | ( | ) | const |
Return dimension.
| const Point& GetEnd | ( | ) | const |
Return upper/right/back corner.
| int GetHeight | ( | ) | const |
| Size GetSize | ( | ) | const |
Return size of extent.
