Common Lisp Mustache Template Renderer

 Inspired by ctemplate and et, Mustache is a framework-agnostic way to render
 logic-free views.
 .
 As ctemplates says, "It emphasizes separating logic from presentation: it is
 impossible to embed application logic in this template language."
 .
 CL-MUSTACHE is a Common Lisp implementation of Mustache v1.1.2+λ.
