Function landon::export_blender_data

pub fn export_blender_data(
    blender_files: &Vec<String>
) -> Result<String, String>

Write the meshes and armatures from a vector of Blender filenames to stdout.

You'll typically use something like

    blender_mesh::parse_meshes_from_blender_stdout
    blender_armature::parse_meshes_from_blender_stdout

to parse the exported data into the data structures that you need.
