Prepared.setArgs should accept range of variants

[schveiguy]

I have a wrapper library that sets parameters based on an array of variants inside my type. I am migrating this to several arrays of variants because they may be built in different orders, but the SQL statement has to have the parameters in a specific order. I had thought maybe I could set all the parameters using setArgs and chain, but it only accepts an array.

This could easily be updated to accept a range, by changing the _inParams[] = args[] call to copy(args, _inParams).
