Feature Request: Area / Volume enclosed by Fermi surface within the Brillouin Zone.

[alpinnovianus]

Hello,

One of the attractiveness of Ifermi that I like is its feature to provide the area of Fermi surface by "ifermi info". I think, the area calculated in this feature is the surface area of the Fermi surface layer.

I wonder, if a feature exists/ can be added in IFermi that calculates the area/volume enclosed by the Fermi surface to the boundaries of the First Brillouin Zone. The feature will be useful to estimate the number of carriers as they are explained this example below from Alloul's Introduction to the Physics of Electrons in Solids textbook.

Thank you very much for your help and consideration.

Apologies for taking so long to get back to you-- I will take a look into this, thank you for the suggestion.
