Module cloud 

Point clouds, and the text formats that carry them: XYZ and PTS.

A cloud is points with what a scanner measured at each: a normal, a colour, and any number of named scalars (intensity, confidence, a deviation an inspection computed). PointCloud holds them side by side, one entry per point in each.

XYZ is a row of numbers per point, separated by spaces, tabs, commas or semicolons; PTS is the same with a line before each scan saying how many rows follow. Neither says what its columns are, so a caller may name them (XyzColumn); otherwise a header line naming them (# x y z nx ny nz, //X,Y,Z,R,G,B) is honoured, and otherwise the column count decides, as read_xyz lays out, and a count that leaves the reading open is refused by name. Neither declares a unit; coordinates come back as written.
