Number field nicknames (reviewed)

The LMFDB supports nicknames, short human-readable names for various fields. Examples include:

• Q, for the rationals $\mathbb Q$
• Qi, for $\mathbb Q(i)$
• QsqrtN, for $\mathbb Q(\sqrt{N})$, as in Qsqrt-5 for $\mathbb Q(\sqrt{-5})$
• QzetaN, for $\mathbb Q(\zeta_N)$, where $\zeta_N$ is a primitive $N$th root of unity.
