A macro to simplify calling inline actions.

Send an inline-action from inside a contract. The send inline action macro is intended to simplify the process of calling inline actions. When calling new actions from existing actions EOSIO supports two communication models, inline and deferred. Inline actions are executed as part of the current transaction. This macro creates an Action using the supplied parameters and automatically calls action.send() on this newly created action. Example:

SEND_INLINE_ACTION( *this, transfer, {st.issuer,N(active)}, {st.issuer, to, quantity, memo} );

The example above is taken from eosio.token. This example: uses the passed in, dereferenced this pointer, to call this.get_self() i.e. the eosio.token contract; calls the eosio.token::transfer() action; uses the active permission of the "issuer" account; uses parameters st.issuer, to, quantity and memo. This macro creates an action struct used to 'send()' (call) transfer(account_name from, account_name to, asset quantity, string memo)

Parameters:

CONTRACT - The contract to call, which contains the action being sent, maps to the account
NAME - The name of the action to be called, maps to a Name
... - The authorising permission, maps to an authorization , followed by the parameters of the action, maps to a data.
