//! Default unit definition.
//!
//! # Base Unit
//! This definition uses the following units as base units.
//!
//! - **`Length`** Metre (m)
//! - **`Mass`** Gram (g)
//! - **`Time`** Second (s)
//! - **`Temperature`** Kelvin (K)
//! - **`Amount`** Mole (mol)
//! - **`Current`** Ampere (A)
//! - **`Luminous`** Candela (cd)
//!
//! Only mass base unit is different from the [SI standards] for ease of parse.
//!
//! # Dimensionless
//! This definition defines some hyphen-like letters to represent the dimensionless dimension
//! because the minus sign (-`\u{002D}`) cannot compose the _Name_.
//!
//! # Angle
//! This definition defines one rotation as one (1).
//!
//! # Head
//! Some units represent pressure as the hight of liquid column.
//! This definition defines `Hg`(mercury) and `Aq`(water).
//! These units are given Pressure / Length dimension.
//! To use these units for pressure unit, multiply length unit.
//! (e.g. "mm Hg", "in. Aq")
//! These units are written with no spaces as "mmHg", "inHg" ordinary.
//! If these spaces are bothering you, zero width space can help.
//! (e.g. "mm​Hg", "in.​Aq")
//!
//! # Deprecated But Acceptable
//! Unicode has many curious characters which represent units.
//! These characters are deprecated because existing only for compatibility.
//! However, this definition adopts these characters positively.
//! Why? Just fun, that's all.
//!
//! # Illegal But Acceptable
//! The [SI Standards] does not allow a orphan _Prefix_.
//! This definition also.
//! But having said that, **_any_** _Name_ can promote with _Prefix_.
//! Yes, we can put the _Prefix_ to the dimensionless dimension!
//! (e.g. "M—" (Mega dimensionless??))
//! This is useful for expressing notations such as "x10<sup>6</sup>".
//!
//! A similar case is a double _Prefix_ , which is not allowed in the [SI Standard].
//! Of course, the syntax of this package implements disallows it also,
//! but some CJK compatible characters which represent the unit include a _Prefix_ already.
//! As a result of this, this definition allows some double prefix.
//! (e.g. "c㎎" (centi milli gram?? (= 10<sup>-5</sup>g)))
//! I can't think of a use for it, though.
