Creates a field path given a data set and the field path in symbolic form conforming to paths
associated with a hash index.

@param dataset the data set
@param type the type name from which to bind the field path
@param path the symbolic field path
@return the field path
@throws IllegalArgumentException if the symbolic field path is ill-formed and cannot be bound
