Title: Added deletion of parentheses pairs to the deletion mutation operator.

Someone (probably Lee) should check this code before merging, particularly the new util function remove-parens-at-point, to make sure it's sound. The methods used there for removing some parens are a bit convoluted, and maybe could be improved with better understanding of zippers.
