create_tf_record not up to date

[skywo1f]

There is no longer a create_tf_record.py in tools. There is a pet create tf record, but that one requires trimap's and may not even be geared towards ssd.

create_tf_record was a script that I wrote, but this repo is very old and no longer maintained (check out the link to the new repo in the readme). I recommend following along with the official TensorFlow object detection API instructions or check out Cloud Annotations
