Add a new SPDataStorage class, and use it in TableContent and CustomQuery:
- SPDataStorage is a class designed for a 2D array of fixed-width data storage, replacing the current method of nested NSMutableArrays. NSFastEnumerator compatible.
- Overall memory overhead for table storage in memory reduced by 1.2-1.4x - this almost gains back the large memory jump seen for 64 bit
- Some operations (adding data, retrieving a single cell's data) are faster than nested NSMutableArrays; some operations (requesting a row as an NSArray) are slightly slower as the data needs to be converted, but overall result is a slight speed gain.
(- Could be used in future to store SQL results in C datatypes, avoiding very high NSObject overhead for numbers and short strings)
