Summary:
This file defines the *Stencil* abstraction: a code-generating object, parameterized by named references to (bound) AST nodes. Given a match result, a stencil can be evaluated to a string of source code.
A stencil is similar in spirit to a format string: it is composed of a series of raw text strings, references to nodes (the parameters) and helper code-generation operations.
See thread on cfe-dev list with subject "[RFC] Easier source-to-source transformations with clang tooling" for background.
