Initialize Message Processing

The auto correct node reads the auto correct table.

1. On the first record, the existence of the required fields is checked. If one is missing, a required field not present workflow exception is issued, which returns a failure to the host client.
2. An internal control is built that lists all fields for each given pass. If a pass field is not specified in the table, only one pass is assumed.
3. It is determined if at least one auto correct field is an ibmNpr MICR field. If so, the ibmNprAutoCorrected flag is updated.
