% elements = GetArgumentsFromLambdaFunction(formula)
%
% Takes
%
% 1. formula, a string representation of a math expression that contains the MathML lambda function
%
% Returns
%
% 1. an array of the components of the lambda function
%
% *EXAMPLE:*
%
% elements = GetArgumentsFromLambdaFunction('lambda(x, x+0.5)')
%
% = 'x' 'x+0.5'
%
% elements = GetArgumentsFromLambdaFunction('lambda(x, y, x + y)')
%
% = 'x' 'y' 'x+y'
