Interpolate recursively a tree of segments

Recursively processes each segment in a tree by:

finding points from neighbouring segments so that the total number of points is between KMIN and KMAX2 by calling tree function MT_get_region().
creating and solving the system of linear equations using these points and interp() by calling matrix_create() and G_ludcmp().
checking the interpolating function values at points by calling check_points().
computing grid for this segment using points and interp() by calling grid_calc().

Todo:: Isn't this in fact the updated version of the function (IL_interp_segments_new_2d)? The function IL_interp_segments_new_2d has the following, better behavior: The difference between this function and IL_interp_segments_2d() is making sure that additional points are taken from all directions, i.e. it finds equal number of points from neighboring segments in each of 8 neighborhoods.

Parameters

info	info for the quad tree
tree	current leaf of the quad tree
bitmask	bitmask
zmax	min and max input z-values
zmaxac	min and max interp. z-values
gmax	min and max inperp. slope val.
c1max	min and max interp. curv. val.

ertot	total interplating func. error
totsegm	total number of segments
