Adding Features

[DRBragg]

This PR is the result of our pairing session. To recap, we added:

• Allowing flow control operators to skip parens when they have single args (i.e. next(1) -> next 1)
• Prevented conditionals with a single line conditional statement as it's only statement from creating a single line conditional (i.e. Dont turn:

if foo
  a ? b : c
end

into

a ? b : c if foo

Please let me know if I missed anything. Thanks again for hanging out. it was a blast pairing with you.
