/**
* Guesses an element based on an array of values

* @example
* inferElementFromValues(
* 'address',
* ['2 Baker Street', '1 Downing street'],
* { number: NumberField, string: StringField }
* );
* // new InferredElement(<StringField source="address" />)
*
* Types are optional: if a type isn't provided, the function falls back
* to the nearest type.
*
* @example
* inferElementFromValues(
* 'content',
* ['<h1>Hello</h1>'],
* { string: StringField } // no richText type
* );
* // new InferredElement(<StringField source="content" />)
*
* Types can be disabled by passing a falsy value.
*
* @example
* inferElementFromValues(
* 'content',
* ['<h1>Hello</h1>'],
* { string: StringField, richText: false }
* );
* // null
*
* @param {string} name Property name, e.g. 'date_of_birth'
* @param {any[]} values an array of values from which to determine the type, e.g. [12, 34.4, 43]
* @param {Object} types A set of components indexed by type. The string type is the only required one
