// Signature class encapsulates a single line of nm output. This line may be
// either an "undefined" name to be resolved, or text or data which resolves
// the unknowns. Some of the features of the Signature class are currently
// unused, such as owner_, which is anticipation of analysis that may lead to
// further code reduction. The premise being that unresolved symbols that are
// defined within otherwise unused code should not be resolved. However this
// information is not available in the output of nm. Further research is
// required.
//
// Signatures are reference counted to avoid duplication.
