Detailed Description

A class implementing ScriptPubKeyMan manages some (or all) scriptPubKeys used in a wallet.

It contains the scripts and keys related to the scriptPubKeys it manages. A ScriptPubKeyMan will be able to give out scriptPubKeys to be used, as well as marking when a scriptPubKey has been used. It also handles when and how to store a scriptPubKey and its related scripts and keys, including encryption.
