# This example describes a regular grid 
#
# object 1 are the regular positions. The grid is 4x2x3. The origin is
# at [0 0 0], and the deltas are 1 in the first and third dimensions, and
# 2 in the second dimension
#
object 1 class gridpositions counts 4 2 3 
origin             0             0             0 
delta             1             0             0 
delta             0             2             0 
delta             0             0             1 
#
# object 2 are the regular connections
#
object 2 class gridconnections counts 4 2 3
#
# object 3 are the data, which are in a one-to-one correspondence with
# the positions ("dep" on positions). The positions increment in the order
# "last index varies fastest", i.e. (x0, y0, z0)   (x0, y0, z1), (x0, y0, z2),
# (x0, y1, z0), etc.
