// Read a mesh from an ascii/binary stl file.

// Templates:
// Scalar type for positions and vectors (will be read as double and cast
// to Scalar)
// Inputs:
// filename path to .stl file
// Outputs:
// V double matrix of vertex positions #V*3 by 3
// F index matrix of triangle indices #F by 3
// N double matrix of surface normals #F by 3
// Returns true on success, false on errors
//
// Example:
// bool success = readSTL(filename,temp_V,F,N);
// remove_duplicate_vertices(temp_V,0,V,SVI,SVJ);
// for_each(F.data(),F.data()+F.size(),[&SVJ](int & f){f=SVJ(f);});
// writeOBJ("Downloads/cat.obj",V,F);
