# C implementation of Levenshtein text distance algorithm, uses RubyInline to call from within Ruby
# Wildly faster than the Text gem's Text::Levenshtein
# Example:

# l = Levenshtein.new
# l.distance 'hello', ' hello'
# => 1

# *** CAPYBARA MATCHERS ***

# To check for content on a page, don't use `include`, use `have_content`:
response.body.should have_content 'A header'
# As opposed to `include`, this Capybara matcher will only look for content

Why you might ask? Well its pretty typical to need to deploy a back end for a webapp or even to have a specific install on your OS.

This makes things clunky if we wanted to say:

1. Visualize solutions in realtime using some js libs on the client side
2. Solve models on the client side of a web app
