 * Parser and evaluator of the scalar expressions like `100% - 50s`.

 * Literals
 *
 * * x%: 0.01 * x * parent value
 * * xs: 0.01 * x * self value
 * * xp: 0.01 * x * padding value
 * * xc: 0.01 * x * current value
 *
 * Operators
 *
 * * `+`

 *
 * Examples
 *
 * * `90%`: 0.9 * parent value
 * * `50s`: 0.5 * self value
 * * `90% - 50s`: 0.9 * parent value - 0.5 * self value
