PowerShell function to get one or more XKCD comics via the API and return it's details as an object. IDs can be passed via the pipeline. Has a -Random switch to select a Random comic with which a -Min and -Max range can optionally be specified. Also has a -Newest switch to return the latest x comics. Mostly an excuse to play with Parameter Sets.

Was curious about how to find the aliases of parameters in Powershell. Turns out also get-help -full and get-help -parameter shows them from PS3 onwards.
