Currently the Tables SDK defaults an integer to serialize as 64bit. However this creates compatibility issues with the other languages - specifically JS, where this will be returned as a string.
We should behave consistently and use 32bit as the default.
This will mean:

• We will need to write some tests to see what the error behaviour is for users providing a numeric value greater than the 32bit max
• We should update any samples, docs etc to describe how to handle this error - i.e. the EntityProperty wrapper to specifying 64bit data type.
• We could think about automatically using 64bit type for large integer values.... but not for first preview.
• At some point we should set up some cross language compatbility tests, again, this can be post preview1.
