====== N ======

###
unsigned integer, read only
###

###
returns the number of determinants saved within the wavefunction.
###

===== Example =====

###
We can define the function:
$$
|\psi\rangle = \left(\frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_2 + (1+I)\frac{1}{\sqrt{4}} a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle,
$$
which has three determinants and //psi.N// thus is equal to three.

==== Input ====
<code Quanty Example.Quanty>
NF=3
NB=0
psi = NewWavefunction(NF, NB, {{"110",sqrt(1/4)},{"101",sqrt(1/4)},{"011",(1+I)*sqrt(1/4)}})
print(psi.N)
</code>

==== Result ====
