Documentation

For documentation of the Valichain class and its own methods, see doc.md. Besides, several methods of String, lodash and chriso/validator are wrapped and used with a prefix followed by a '$'. The first argument of the wrapped function is automatically replaced by the current value being validated, so do not pass it.

Samples of usage of wrapped functions

String's functions:
- x.trim() => new V().s$trim().validate(x)
lodash's functions:
- .isNumber(x) => `new V(). $isNumber().validate(x)`
chriso/validator's functions:
- validator.isEmail(x) => new V().v$isEmail().validate(x)
