ValidateValue to use string or interface?

[tferracina]

func (dt *Datatype) ValidateValue(value interface{}) bool { switch dt.ValueCheck { case "URL": return validateURL(value) case "in{1,2,3,4,5}": // TEMP return validateInRange(value, 1, 5) case "mail_ping": return validateEmail(value) case "phone": return validatePhone(value) case "file_exists": return validateFileExists(value) case "date": return validateDate(value) default: return false } }

We should struct because we can combine metadata and methods
