binary search tool: Change verify_level to boolean
Previously, the user could run multiple levels of verification. This
would essentially repeat verification multiple times. It's unsure why a
user would want to set verify_level to any value other than 0 or 1. Thus
verify_level is more appropriate as a boolean.
