Arctic doesn't have library_exists method #660

Description of problem and/or code sample that reproduces the issue

There is no "library_exists('my_library_name')" method, which forces users to use the expensive: 'my_library_name' in a.list_libraries()

Instead use a lightweight "library_exists()" method (no regex support, just exact lib name match), which wraps get_library().
