====== NB ======

###
unsigned integer, read and write
###

###
**Current version does not suport bosons, i.e. NB must always be //0//.**
###

###
An integer representing the number of Bosons in the basis. For wavefunction //psi//, index //0// to //psi.NF-1// refers to Fermions, index //psi.NF// to //psi.NF+O.NB-1// refers to Bosons. Changing this number changes the wavefunction. If the new number of Bosons is smaller than the old number all modes referring to Bosons larger than //NB-1// will be removed from the determinants.
###

===== Example =====

###
We can define the function:
$$
|\psi\rangle = \left(\frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_2 + (1+I)\frac{1}{\sqrt{4}} a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle,
$$
changing the number of bosons in the basis from 0 to 2 currently results in an error.

print(psi.NB)
psi.NB=2
