Fixed a small mistake in the C code.

Replaced `sprintf`

with `snprintf`

in the C
code.

New function

`hullMesh`

to extract the vertices and the faces of a 3d convex hull.Updated the vertices of Leonardo da Vinci’s 72-sided sphere; the new ones are more accurate.

New function

`dihedralAngles`

which computes the dihedral angles of a 3d convex hull.New argument

`angleThreshold`

in the`plotConvexHull3d`

function. Edges whose corresponding dihedral angle is greater than`angleThreshold`

are removed from the plot.

- New function
`cxhullEdges`

, which computes only the vertices and the edges of a convex hull (for speed gain and less memory consumption).

New function

`hullSummary`

, which returns a summary of a 3D triangulated convex hull.Now, the

`facesColor`

argument of`plotConvexHull3d`

can be a vector, allowing to assign different colors to the faces. See the README file for examples.The

`plotConvexHull3d`

function has a new argument`palette`

; it allows to decorate the faces with a color gradient.Updated the README file.

New function

`plotConvexHull3d`

, to easily plot a 3D convex hull, with a correct orientation of the facets.A couple of other new functions, e.g.

`EdgesAB`

, which returns a matrix representing the edges and indicating which edges are on the border of the convex hull. These functions are used by`plotConvexHull3d`

, they are not of great interest otherwise.

- New component of facets:
`orientation`

, indicating the facet orientation.

- Maintenance release.

- First release.
