Feature 320 update schema mpr orank (#322)

* Fix pwd value

* Issue #320 updates for MPR and ORANK linetype changes

* Fix indentation

* Issue #320 updates to MPR and ORANK linetypes

* Issue #320 schema updates to reflect changes to MPR and ORANK linetypes.  Test, config, and test data.

* Skip testing MPR linetype in reformatter.  There were changes to the columns: names and additional columnsthat will break this test until the METreformat module is updated.

* Issue #320 fixed syntax error

* Add pip install of pytest

* Issue #320 tests to verify that the renamed column names were created
and the new columns are present.

* Issue #320 config file used to test that the new schema was loaded.

* Update update_for_6_0_beta6.sql
