Builds a short abstract of a supplied text by extracting the first couple of sentences and trimming off punctuation etc.
require 'abstractifier'
abstractifier = Abstractifier.new
#=> #<Abstractifier:0x007ffe350993c8 @elider="…", @max_length=250, @min_length=80>
abstractifier.abstractify("This is a longish piece of text. It contains several sentences. It is long enough that we will need to build an abstract for it, but the first two sentences are quite short, so we will need to include some content from the third sentence so that we can fulfill both our minimum and maximum abstract lengths.")
