Broken with export const

[ckknight]

With esformatter 0.9.0 and esformatter-var-each 2.1.0:

Input:

export const WAT = {};

Output:
Cannot read property 'indexOf' of undefined

Can you provide the rest of the stack trace?

[ckknight]

No, I cannot.

$ $(npm bin)/esformatter tmp.js 
Cannot read property 'indexOf' of undefined

Alright, we will take a look at reproducing this issue by the end of next weekend.

I have reproduced the error on dev/export.support but I believe it looks like the code won't be easily resolvable.

We are going to want to support a syntax like:

export const a = 'hello', b = 'world';

which we would convert to:

export const a = 'hello';
export const b = 'world';

The root cause of the problem is we currently assume that there is a single VariableDeclaration node (e.g. var, let, const). However, when we add an export there are 2 nodes that we need to clone to the head of each var (i.e. ExportNamedDeclaration and VariableDeclaration).

I'm going to mark this issue as "help wanted".
