Add support for `ExpressionJSON`
As @rocky said we should add support to ExpressionJSON.
I just need some examples to see how ExpressionJSON is with Graphics3D, maybe @mmatera could help here?
Something like this:
In[4]:= ExportString[Graphics3D[{Sphere[]}],"ExpressionJSON"]
Out[4]= [
"Graphics3D",
[
"List",
[
"Sphere",
[
"List",
0,
0,
0
]
]
]
]
In[4]:=ExportString[Plot3D[x*y,{x,0,2},{y,0,2}],"ExpressionJSON"]
Out[4]=
[
"Graphics3D",
[
"GraphicsComplex",
[
"List",
["List",

Essentially, is just as any ExpressionJSON: first takes the FullForm of the expression, and then builds a javascript nested list.
@mmatera thanks!

Yes, it looks like just a list of the element name and its leaves.
