% Adds a simple shock to the forecast scenario plan
%
% INPUTS
% o plan [structure] A structure describing the different shocks and the implied variables, the date of the shocks and the path of the shock (forecast scenario).
% The plan structure is created by the functions init_plan, basic_plan and flip_plan
% o exogenous [string] A string containing the name of the exognous shock.
% o expectation_type [string] A string indicating the type of expectation: 'surprise' for an unexpected shock, and 'perfect_foresight' for a perfectly anticpated shock.
% o date [dates] The period of the shock
% o value [array of double] A vector of double containing the values of the exogenous variable
%
%
% OUTPUTS
% plan [structure] Returns a structure containing the updated forecast scenario.
