Define a method starts_with_consonant?(s) that takes a string and returns true if it starts with a consonant and false otherwise. (For our purposes, a consonant is any letter other than A, E, I, O, U.) NOTE: be sure it works for both upper and lower case and for nonletters! Run associated tests via: $ rspec -e '#starts_with_consonant?' spec/part2_spec.rb
