This method is useful when attempting to account for the fact that not

strict regimen. Some rooms will be used more than expected and others less.
This method uses a random number generator and gaussian distribution to
generate loads that vary about the mean program. Note that the randomly
generated values can be set to something predictable by using the native
Python random.seed() method before running this method.
In addition to diversifying load values, approximately 2/3 of the schedules

schedule_offset (1/3 ahead and another 1/3 behind).

schedule_offset: A positive integer for the number of timesteps at which all
schedules of the resulting programs will be shifted - roughly 1/3 of
the programs ahead and another 1/3 behind. (Default: 1).
timestep: An integer for the number of timesteps per hour at which the
shifting is occurring. This must be a value between 1 and 60, which
is evenly divisible by 60. 1 indicates that each step is an hour
