Recent work

• Link with lldb reported by llvm-config on MacOS: no need to use the XCode one, can work with custom builds or lldb installed with Homebrew
• Fixed tests and Travis intergration
• LLNODE_DEBUG=true to print details of failures during symbol loading, turned on in Travis
• Loading symbols with shared libraries: can work with libv8 + d8 built with post-mortem support

JS API

• Original work by @rnchamberlain, rewrote with NAN and some API changes, e.g. use iterators for instance lists to save memory.
