Show at least some of what's in a node by default

[Keno]

This output isn't super helpful in interactive use:

invlist = findall("//...", xdoc)
1-element Array{EzXML.Node,1}:
 EzXML.Node(<ELEMENT_NODE@0x00007ffbac7a7d20>)

It would be nice to print at least some of the node properties (e.g. the tag name).

Thanks. Now it shows the name of element and attribute nodes like EzXML.Node(<ELEMENT_NODE[name]@0x00007ffbac7a7d20>).
