+/// Utility to construct an invoice. Generally, unless you want to do something like a custom
+/// cltv_expiry, this is what you should be using to create an invoice. The reason being, this
+/// method stores the invoice's payment secret and preimage in `ChannelManager`, so (a) the user
+/// doesn't have to store preimage/payment secret information and (b) `ChannelManager` can verify
+/// that the payment secret is valid when the invoice is paid.
