% index = matchFunctionName(expression, name)
%
% Takes
%
% 1. expression, a string representation of a math expression
% 2. name, a string representing the name of a function
%
% Returns
%
% 1. the index of the starting point of 'name' in the 'expression'
%
% *EXAMPLE:*
%
% index = matchFunctionName('f*g', 'g')
%
% index = []
%
%
% index = matchFunctionName('add(d,g_1)', 'add')
%
% index = 0
%
%
% index = matchFunctionName('add(add(a,b), c)', 'add')
%
% index = [1, 5]
%
%
%
% *NOTE:* This differs from the 'strfind' function in that it checks
% that the name is used as a function call.
