/ CodeInjector is an interface which is responsible for injecting AST
/ of function definitions that may not be available in the original source.
/
/ The getBody function will be called each time the static analyzer examines a
/ function call that has no definition available in the current translation
/ unit. If the returned statement is not a null pointer, it is assumed to be
/ the body of a function which will be used for the analysis. The source of
/ the body can be arbitrary, but it is advised to use memoization to avoid
/ unnecessary reparsing of the external source that provides the body of the
/ functions.
