Workspace Method mblock_dlos_gridUniformCircular

Description

Gives mblock_dlos_grid roughly circular coverage, with uniform spacing.

The method considers points on a regular grid with a spacing set by
GIN *spacing*. All points inside a radius from (0,0) are included in
mblock_dlos_grid. The positions in mblock_dlos_grid thus covers
a roughly circular domain, and cover the same solid beam angle.
The radius is adjusted according to *spacing' and *centre*, but is
ensured to be >= *width*.

Note that the method assumes that width is small and the solid beam
angle does not change with distance from (0.0).

Defualt is to consider grid positions of ..., -spacing/2, spacing/2, ...
If you want to have (0,0) as a point in mblock_dlos_grid, change
*centre* from its default value.
