function Transformation = ChangeTransformFunction(Transformation,VariableNames)
% ChangeTransformFunction: Changes the the variable dependent transformation functions from
%                          the "fcn" and "partial" fields to the "annualizefcn" and 
%                          "annualizepartial" field values.
%
% USAGE:
%
%       Transformation = ChangeTransformFunction(Transformation,VariableNames)
%
% REQUIRED INPUT:  Transformation (structure) with field names. The field name to use is determined
%                                 by CurrVariable. This field name has subfields "fcn", "annualizefcn",
%                                 "initial", "x", "invertfcn", "invertinitial", and "invertx".
%
%                  VariableNames (string matrix) of dimension kxK with the names of the variables.
%
% REQUIRED OUTPUT: Transformation (structure) with field names. The field name to use is determined
%                                 by CurrVariable. This field name has subfields "fcn", "annualizefcn",
%                                 "initial", "x", "invertfcn", "invertinitial", and "invertx".
