Hey Everyone,

Just FYI, builds from today onward have a little search() function (see example023.scad) and support for vector dot-product (vec*vec=scalar), matrix*vec, vec*matrix and matrix*matrix operator support I coded up.

Next on my list are identity(i), pow(square_matrix,i), determinant(square_matrix), and inverse(square_matrix) to make forward- and inverse-kinematics a little easier.

Enjoy!

Andrew.
