ISEVENFUNCTION True if function is even
Usage: t=isevenfunction(f);
t=isevenfunction(f,tol);
ISEVENFUNCTION(f) returns 1 if f is whole point even. Otherwise it
returns 0.
ISEVENFUNCTION(f,tol) does the same, using the tolerance tol to measure
how large the error between the two parts of the vector can be. Default
is 1e-10.
Adding the flag 'hp' as the last argument does the same for half point
even functions.
