// Implementation of the Mustache templating language supports version 1.4.2
+// currently relies on llvm::json::Value for data input

//
+// Current Features Supported:
+// - Variables
+// - Sections
+// - Inverted Sections
+// - Partials
+// - Comments
+// - Lambdas
+// - Unescaped Variables
+//
+// Features Not Supported:
+// - Set Delimiter
+// - Blocks
+// - Parents
+// - Dynamic Names
+//
+// Usage:
+// - Creating a simple template and rendering it:
+// \code
+// auto Template = Template::createTemplate("Hello, {{name}}!");
+// Value Data = {{"name", "World"}};
+// StringRef Rendered = Template.render(Data);
