Build octree fails on "obj_info" property

[andre-nguyen]

I have a .ply file exported from CloudCompare so in my ascii header there was the line:

obj_info Generated by CloudCompare!

This made the octree builder fail with the message

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error(InvalidInput("Invalid line
: obj_info Generated by CloudCompare!\n"), State { next_error: None, backtrace: None })', src/libcore/re
sult.rs:997:5
note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

After deleting that line manually the octree builder runs fine. This error is reproducible using the standford bunny dataset: http://graphics.stanford.edu/data/3Dscanrep/

Indeed, obj_info files should just be ignored.
