Odors
In Nock, a noun is an atom or a cell. In Hoon, it's not so simple.
In Hoon, @ is the atom type and ^ is the cell type, but it doesn't end
there. @ can be followed by lowercase letters to determine exactly what kind
of atom we're talking about, and a capital letter to limit the size. Here are
the top-level odors used in hoon.hoon:

When writing a numeric literal, it MUST be broken up into groups (3 for decimal, 4 for hex or binary) separated by a period, and MUST NOT start with a leading zero (unless the whole number is 0). Anything else is a syntax error.
