# 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
# the most up-to-date version of PowerView will always be in the dev branch of PowerSploit:
# https://github.com/PowerShellMafia/PowerSploit/blob/dev/Recon/PowerView.ps1
# 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
