## Description
The gis-distance library allows you to calculate geographic distance between
two points using the formula of your choice.

## Synopsis
```ruby
require 'gis/distance' # or 'gis-distance'
# New York to Los Angeles
gis = GIS::Distance.new(40.47, 73.58, 34.3, 118.15)
# Set the formula of your choice
gis.formula = 'cosines'
gis.formula = 'haversine'
+gis.formula = 'vincenty'
p gis.distance # Kilometers
p gis.distance.mi # Miles
```
## Available Formulas
* haversine (https://en.wikipedia.org/wiki/Haversine_formula)
* cosine (https://en.wikipedia.org/wiki/Law_of_cosines)
+* vincenty (https://en.wikipedia.org/wiki/Vincenty%27s_formulae)

+## Miscellaneous
+Ruby 2.x was dropped from the test matrix as of version 1.2 because of
+incompatibility with bundler. This library should still work fine with
+older versions of Ruby, but you should strongly consider upgrading at this
+point since Ruby 2.x is now EOL.
