Use nan helpers to set exports

Fixes compilation errors when built on Node.js master with V8 7.4.

`NAN_EXPORT()` requires the function name exported to JavaScript land
and the exported C++ method to match. Change the exported C++ methods
to begin with a lower case character to preserve the existing casing of
the name exported to JavaScript.
