public class CoordinateAxis1D extends CoordinateAxis
If this is char valued, it will have rank 2, otherwise it will have rank 1.
If string or char valued, only getCoordName() can be called.
If the coordinates are regularly spaced, isRegular() is true, and the values are equal to getStart() + i * getIncrement().
This will also set "cell bounds" for this axis. By default, the cell bounds are midway between the coordinates values, and are therefore contiguous, and can be accessed though getCoordEdge(i). The only way the bounds can be set is if the coordinate variable has an attribute "bounds" that points to another variable bounds(ncoords,2). These contain the cell bounds, and must be ascending or descending as the coordinate values are. In this case isContiguous() is true when bounds1(i+1) == bounds2(i) for all i.
