'''
The State Compiler is used to execute states in Salt. A state is unlike
an execution module in that instead of just executing a command, it
ensures that a certain state is present on the system.
The data sent to the state calls is as follows:
{ 'state': '<state module name>',
'fun': '<state function name>',
'name': '<the name argument passed to all states>'
'argn': '<arbitrary argument, can have many of these>'
}
