3. Please describe how your code solves the related issue.

   This PR adds support for the contains_null parameter to structured ArrayType objects. By default semi-structured and structured array columns allow null values. By setting contains_null in the ArrayType initilization we can specify that no elements of the array are null. This likely should not be merged until the testing gap commented below is closed.
