## VALIDATOR

@name validator

@description support multiple names, multiple values and multiple type check
@option if nameString ends by $ sign it is considered optional

@function validator([Objects])
@return {error|true/false|testMode} depend on mode (see prop mode)
@param {} mode normal (default) | test (TODO) | boolean
@param {} name 'myName' || [{myVar1: 'blah, myvar2: myvar2}], support multiple names / values
@param {} value myVar,
@param {string} myVar myVar, instead of name / value
@param {array} in ['blah', 'otherPossibleValue', true], equal ONE OF THESE values
@param {any} eq exactly equal to in, both support string or array of values
@param {any} neq not in, both support string or array of values
@param {number} lte 3, less than or equal
@param {number} gte 1, greater or equal
@param {number} lt 3, less than
@param {number} gt 1, greater
@param {string|string[]} type
 * possibleTypes: object, number, string, boolean, array, date, dateInt8, dateInt12, dateInt6, time, objectId (mongo), humanReadableTimestamp, buffer
 * Notes: multiples value is an OR, /!\ Array is type 'array' and not 'object' like in real JS /!\
@param {regExp} regexp /regexp/, test against regexp
@param {number} minLength for string, array or number length
@param {number} maxLength
@param {number} length
@param {boolean} optional default false
@param {boolean} emptyAllowed default false (to use if must be set but can be empty)
@param {boolean} mustNotBeSet this one must not be set
@param {any} includes check if array or string includes value (like js .includes())

@example
    validator(
        { myNumber : 3, type: 'number', gte: 1, lte: 3 }, // use the name directly as a param
        { name: 'email', value: 'nameATsite.com', regexp: /[^\sAT]+AT[^\sAT]+\.[^\sAT]/},
        { name: [{'blahVar': blahVarValue, 'myOtherVar': myOtherVarValue}], type: 'string'} // multiple names for same check
    )
