/**
* This is an example implementation for the hook. Preforms actions when converting a node based on it's type.
*
* @param $data
* An array containing information about the conversion process. The keys are
* - dest_node_type The destination type of the node
* - node The node object
* - Any other information passed by $op = 'options' or $op = 'options validate'
* @param $op
* A string containing the operation which should be executed. These are the possible values
* - insert Operations which should be run when the node is transferred to the new node type.
* Usually for transferring and adding new node information into the database.
* - delete Operations which should be run after the node is transferred to the new node type.
* Usually for deleting unneeded information from the database after the transfer.
* - options Configuration elements shown on the conversion form. Should return a FAPI array.
* - options validate Validation check on the options elements.
* @return
* Should return a FAPI array only when using the options operation.
