unify `1-getting-started/6_object_wrap` samples to implements the same logics. by UrielCh · Pull Request #539 · nodejs/node-addon-examples

The 3 example in 1-getting-started/6_object_wrap do not implement the same addon.

  • Nan implement value() as a function
  • Napi implement value as a field
  • node-addon-api implement value() as a function

this PR implement value as a Read and Write field and add a getValue() as a function.

the 2 accessor (set and set) and the getter are now called in the addon.js.

the 3 addon.js files are now the same.

note:
the NaN::InstanceAccessor wasn't use in any example before this PR.
