Added Words table to database

We created a migration. In fact, not to brag, but Danny and I created this migration 10 times so that we now know the syntax for creating an Activerecord migration backwards and forwards.  Wohoo!
Read dictonary of words from text file to databse in seeds.rb

After migrate and db creation, in seed file, read text file line
by line, amke a new word row entry per line of text.

text = File.open(APP_ROOT.join("db", 'test_dictionary.txt'))

text.each_line do |line|
  Word.create(word: line)
end
