cdb_Update for numeric and calculated data

[mark_talluto]

Hi Sid,

Thank you for responding to Peter. That is so helpful when we are all sharing information.

I completed the cdb_calcUpdate() funtions. They work on local and cloud. They return the result of the calculation so you can reliably get the result without risking the integrity of the data with a read.

I still need to create documentation for the API and I need to update the regions with the changes. I'll work on those tomorrow.
