# What is it?
# => Helper methods for Apartment::Tenant gem
# How does it work?
# * bin/rails console => auto-loads and asks to switch tenant
# * T.ask => anytime in console, to switch tenant from a list
# * T.me => same as Apartment::Tenant.current
# * T.hash => hash of tenants. Example: { 0 => "public", 1 => "tenant-a" }
# * T.names => array with all existing tenant names from DB
# * T.exists?(arg) => returns true/false if `arg` exists as tenant in DB
# * T.switch!(arg) => same as Apartment::Tenant.switch!
