Detailed Description

Implement my versions of MPL boolean operations with many arguments.

4-2. Extend the implementation of logical_or and logical_and metafunctions
     from exercise 4-1 to accept up to five arguments.

Todo:

Same logic holds true for logical_and, but with false_ instead of true_. Go back and write logical_and some time.
