Creator of predicate for Record type

isSpecificRecord

this function is provided to create predicate on specific record type.

e.g const Action = Record({ type: null, point: null}) const isAction = isSpecificRecord(Action);

isSpecificRecord is curried so isAction is currently a function waiting for a parameter. the parameter is the value which needs to be tested.
