Several edge types in shortestpath()

[dargolith]

Hi,

It would be nice to specify more than one allowed edge type for shortestpath. It would mean: "Give me the shortest path only using one of these edge classes".

Is there a reason for it not being supported?

I only briefly glanced at the code, but it seems to me like the inner algorithm itself already supports it.

String   edgeType;
String[] edgeTypeParam;

...

ctx.edgeType = null;
if (iParams.length > 3) {
    ctx.edgeType = iParams[3] == null ? null : "" + iParams[3];
}
ctx.edgeTypeParam = new String[] { ctx.edgeType };

Seems like ctx.edgeTypeParam is the one being used later in the code and it is an array already. Would it work by just allowing an array argument for the function?

#7842 requested the same change. Fix is in 3b660af and will be released in 2.2.30.
