#433 Make Array method for fixed length lines

[Jon Wolfers]

DBX data files have a header followed by fixed length lines.
It would be helpful if there was an option on the makearray method (either of the stream OR string class) that allowed for the breaking up of the stream, or string into fixed length lines with each of these lines assigned to an element of the returned array.
At the moment they are seperated on the basis of a seperator character.

If the method was implemented for the stream class, then where the charin method has been used, the data in the first element of the array should start at the current position of the read pointer.
thanks,

Jon
