A simple raycast algorithm implementation in Elixir

ExRaycast is the implementation of ray casting algorithm to determine if a point is in the polygon or not. It also includes a simple implementation that can be used for the cases where there's a hole in the polygon.

This was used to test westar kml using Elixir and is not perfect.

If available in Hex, the package can be installed as:

1. Add ex_raycast to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:ex_raycast, "~> 0.1.0"}]
end
```

2. Ensure ex_raycast is started before your application:

```elixir
def application do
  [applications: [:ex_raycast]]
end
```
