 *** Better Parenthesis with Text Object
 I took the following clever idea and code from [[http://blog.binchen.org/posts/code-faster-by-extending-emacs-evil-text-object/][this essay]] from Chen Bin for creating a ~xig~ to grab code within any grouping characters, like parens, braces and brackets. For instance, ~dig~ cuts the content inside brackets, etc. First, we need a function to do the work (I changed the original from =my-= to =ha-= so that it is easier for me to distinguish functions from my configuration):
