Vapor RenderDriver implementation for Stencil.

To add VaporStencil, add the following package to your Package.swift.

Package.swift

.Package(url: "https://github.com/tannernelson/vapor-stencil.git", majorVersion: 0)

Then set the StencilRenderer() on your View.renderers for whatever file extensions you would like to be rendered as Stencil templates.

main.swift

import VaporStencil

//set the stencil renderer
//for all .stencil files
View.renderers[".stencil"] = StencilRenderer()
