# Revives factory or factory property from step to real value
# @note any factory is building once per scenario for the same number.
#  if number is ommited, then it is assigned to 0 number.
#  Built factories are stored in Howitzer::Cache and cleared after each
#  scenario automatically
# @example
#  'When I fill first name field with FACTORY_USER1[:first_name] value'
#  #=> build(:user).first_name

#   | FACTORY_USER1[:name] | FACTORY_USER1[:email] |
