%% @doc Creates an experiment template.
%%
%% An experiment template includes the following components:
%%
%% <ul> <li> Targets: A target can be a specific resource in your Amazon Web
%% Services environment, or one or more resources that match criteria that
%% you specify, for example, resources that have specific tags.
%%
%% </li> <li> Actions: The actions to carry out on the target. You can
%% specify multiple actions, the duration of each action, and when to start
%% each action during an experiment.
%%
%% </li> <li> Stop conditions: If a stop condition is triggered while an
%% experiment is running, the experiment is automatically stopped. You can
%% define a stop condition as a CloudWatch alarm.
%%
%% </li> </ul> For more information, see Experiment templates in the Fault
%% Injection Simulator User Guide.
