Compatibility issues with ubjson format about jsonlab

[fangq]

@jayendra13, I apologize for the delay. I was out of town for a conference last week and did not get chance to write a detailed reply.

This compatibility issue is known. As described in Issue #6 and this README section

https://github.com/fangq/jsonlab/blob/master/README.txt#L366-L368

jsonlab utilizes an unofficial N-D array syntax to store complex arrays. This was originally proposed in this ubjson mailing list, but the upstream author of the specs had no interest to adopt

Basically, in this extended syntax, the array dimension grammar (#) in UBJSON can be followed by an array object [[] ... []]. If this is detected, jsonlab will treat it as N-D array and reshape the 1D data stream into N-D based on the specified dimensions.

I felt that this extended syntax is extremely convenient when storing N-D arrays especially in matlab. This syntax also allows one to pre-allocate the array before reading an N-D array. If one has to do it with UBJSON Draft 9-12, he/she has to encapsulate each inner loop segment of an array using embedded array grammar. This is very inconvenient and hard to process.

I don't have a time table to fix the above Issue #6 because, in my opinion, the unofficial N-D array syntax in jsonlab is way more convenient for arrays of 2D or higher dimensions.
