hash_from_now.rb

# this method will take in a hash of date fragments and turns it into a date from_now
# I can't think of a more descriptive name at the moment, i will just use an example:

#>> future_date_from_hash(:days => 5, :minutes => 3, :month => 1)
#eq (5.days + 3.minutes 1.month).from_now

def future_date_from_hash(hash = {})
  hash.to_a.map{|d| d.last.send(d.first)}.inject(&:+).from_now
