Spice things up a little by putting in a vitals and a power test case, testing out the command send command

TODO: repackage the xml object into intended powershell objects
Output types:
-xCATData
-xCATNodeData
-xCATNoderangeData
xCAT Data has error and data not contained within a node
xCATNodeData has error and data contained within a node
xCATNoderangeData will be an aggregation of the above (to be treated differently ps1xml wise hopefully)

The original noderange will be chucked into any of these, for Merge-xCATNodeData to have as a hint maybe
