# In order to measure and log execution of our service, we just need to 'prepend Measurable' module
# Example:
# ```
# class DummyService
# def execute
# # ...
# end
# end
# DummyService.prepend(Measurable)
# ```
#
# In case when we are prepending a module from the `EE` namespace with EE features
# we need to prepend Measurable after prepending `EE` module.
# This way Measurable will be at the bottom of the ancestor chain,
# in order to measure execution of `EE` features as well
# ```
# class DummyService
# def execute
# # ...
# end
# end
#
# DummyService.prepend_if_ee('EE::DummyService')
# DummyService.prepend(Measurable)
# ```
