Add an option for saving the meshes as obj

Right now it seems not possible to do it via CREO, but we could convert a step created by creo into an obj using other API such as:

Exporting the step with quilts seems feasible:

• Add geometry flags for step export #147

But looking here:

• https://www.ptc.com/de/support/article/cs69676?&as=1

It states that "Not part of the Creo Parametric Toolkit functionality."

Here it is the proposed workaround:

Workaround: run macro to export.
 - Use Tools > Find command to select required coordinate system.
 - Check if the model to be exported is an assembly or contains quilt. If so, additional macro needs to be used to select component or quilt.
