◆ main()

int main ( )

Test of the binary reader. The files used is STL file with containing one triange.

This code users BinaryReader to open a binary file called SimpleTrianlge.stl and read in currently the single tringle from this file. The triangle was created using nclab.org and contains a single triangle with normal (0,0,1) and vertex (0,1,0), (1,0,0) and (1,1,0). This is currently a UnitTest as does not require selftest data; however, it does require he file SimpleTrianlge.stl to exist
