function value = piecewise(val1, test, val2)
% value = piecewise(value1, test, value2)
% 
% Takes
% 
% 1. value1, the value to return if the test is true
% 2. test, a boolean test that will return true or false
% 3. value2, the value to return if the test is false
% 
% Returns
% 
% 1. value = 
%   - value1, if test returns true
%   - value2, if test returns false
%     
% *EXAMPLE:*
% 
%               value = piecewise(3, 1<2, 4)
%               value = 3
%               
%               value = piecewise(3, 1>2, 4)
%               value = 4
%               
% *NOTE:* This function provides the functionality of the MathML 'piecewise' function.
