Construct a new coercer that will attempt to coerce a list of values such that all members are of one of the given types. The container may also optionally be coerced to a Set. An arbitrary coercion method may be supplied, which will be passed the entire collection as a parameter and should return a new collection, or may return the same one if no coercion was required.

@param types [Array<Class>,Set<Class>] list of allowed types,

  also specifying the container type

@param method [call,parse] method by which values should be coerced

Coerce the given value.

@param value [Array<String>] collection of values to be coerced @return [Array<Object>,Set<Object>,InvalidValue]

  the coerced result, or an instance
  of {InvalidValue} if the value could not be coerced.

Assert that the value has been coerced successfully.

@param value [Object] a coerced result returned from {coerce} @return [true,false] whether or not the coerced value

  satisfies type requirements.
