Adding new functions to Node

[suntong]

Basically, all functions defined in

https://github.com/antchfx/xmlquery/blob/e73954f0f504eaf97f73ad62a4c52419e304b7bd/node_test.go#L11-L69

are necessary for me for my node navigation & checking, and I'd like to move them into node and expose them,

while changing (in node.go alone)

• testNode to func IsNode(n *Node, expected string) bool
• testAttr to func HasAttr(n *Node, expected string) bool and
• testValue to func HasValue(val, expected interface{}) bool

OK?

It makes no sense to add IsNode, HasAttr and HasValue to node.go. Node already have InnerText() and SelectAttr() to help finish these logical operation.

OK. I'll leave them alone.

How about the rest of the functions then?
