Feature request: `toJson`-method

[Asbjørn Dyhrberg Thegler]

Hi there,

There is already a toString-method, but if we want to be able to supply the JSON.stringify-options ourselves, it's currently very complicated.

I'll supply a MR shortly, hopefully this should be simple. :)

Edit: MR supplied

+1 this function would be very valuable
