Description

I have just added the approx pts preprocessing fns to CoCoA-5.
This issue is about deciding the most appropriate interface; right now it is just what was easiest for me to impl.

Points and tolerances are specified as matrices (automatically guarantees that all coords are in the same ring, and that the point all have the same number of coords -- do need to check that points and tolerances are compatible). Result is as a list of lists currently; shoudl this be a matrix too?

Each point is represented as a row in the matrix.

Opinions?

Manual for PreprocessPts is wrong. I had a look, but I don't know how to fix it.
(syntax talks about LIST, but should be MAT; examples give error incompatible dimension)

I have corrected the spurious error -- forgot to invert a condition when changing an assert into if (check) CoCoA_ERROR(...). Also cleaned the arg checking code -- now a separate routine which each fn calls (rather than repeated copies of the code).

I have updated the C5 manual; at some point in the past I had already made the design decision to represent sets of points as matrices (one row per point). This automatically guarantees coherence of ring and number of coords.

Moving to feedback.
