Casper Copy Key

This is a simple Casper Session script that copies a value from source named key to target named key.

To use it you have to define three arguments:

• source_key - the key from which the value will be copied,
• target_key - the key to which the value will be copied,
• allow_overwrite_target - a boolean value that determines if the target key can be overwritten.

Note that it copies only the Key not the value underneeth it. It means that both source_key and target_key will point to the same value after the script is executed.
