Format

I ran mix format and added some parens in mix.exs to silence warnings:

warning: variable "package" does not exist and is being expanded to "package()", please use parentheses to remove the ambiguity or change the variable name
  mix.exs:9

warning: variable "description" does not exist and is being expanded to "description()", please use parentheses to remove the ambiguity or change the variable name
  mix.exs:10

warning: variable "deps" does not exist and is being expanded to "deps()", please use parentheses to remove the ambiguity or change the variable name
  mix.exs:11

Darn, just found #19 which already fixes warnings. :(
