Broadcasting

[leotrs]

We have discussed this multiple times in one way or another. Essentially, it'd be great to have calls such as

>>> H.nodes.degree(order=1).aslist()
[0, 0, 0, 0, 1, 1, 0, 0]

automatically broadcast when asking for more than one order:

>>> H.nodes.degree(order=[1,2]).aslist()
# -> ?

Currently, the only way of getting the degree in two different orders is by using the multi method which is super clunky:

>>> nn = H.nodes
>>> nn.multi([nn.degree(order=1), nn.degree(order=2)]).aspandas()
   degree(order=1)  degree(order=2)
1                0                1
2                0                1
3                0                1
4                0                0
5                1                0
6                1                1
8                0                1
7                0                1

It would be much better for the call H.nodes.degree(order=[1,2]) to auatomatically broadcast and return a MultiStat object.
