Subject: [PATCH] After adding edges in Ng_STL_InitSTLGeometry, set readedges
 size to 0.

The global variable readedges that the API uses doesn't clear itself after the Ng_STL_Geometry * has been initialized.
It would cause problems for people who wish to initialize another Ng_STL_Geometry if they used Ng_STL_AddEdge in before their previous initialization.
