Jonathan Hamilton b426fafff6 Fix some Node::operator[] regressions from 0.5.1 ... "const Node Node::operator[](const Key& key) const" changed from returning new empty node if the key was missing in 0.5.1 to returning a shared 'zombie' node in 0.5.2 to resolve a memory leak. (Specifically 1025f76df1 was where this was introduced) This caused some regressions where this 'zombie' object threw exceptions in some functions where the 'empty' object would not. This change fixes the Node::as(fallback) method (to return the 'fallback' instead of throwing an exception) and the Node::begin()/Node::end() methods to return default-constructed iterators (so begin() == end() in such cases) instead of another exception.		2015-06-08 11:47:10 -07:00
