Confusing readme on is_sandbox

[tayloramurphy]

The readme in the code says The is_sandbox should always be set to "true" if you are connecting Production account of NetSuite. Set it to false if you want to connect to SandBox acccount.

Looking at the code though it seems like it appends _SB1 if this is true. Which is the proper way this should work?

Had the same issue, you should set it to "false" if you are connecting to a Production environment, "true" if otherwise
