	- More complex filters for translate and related methods
	Updated depdendencies
        Bug fixes
        - maptables attribute of recycled idtype not reset
	Still trying to track down FAILs seen by David Cantrell
	  (reports 34101829, 34102877, 34457224)
	Test changes
	- More test cleanup subsequent to fixing of 'implicit masters' bug
        - Fixed boilerplate & pod tests


1.13_04 2013-09-23
        Bug fixes
        - Implicit master created in application and passed into Babel
	  constructor not processed by make_implicit_masters and thus not set up
	  properly
	Still trying to track down FAILs seen by David Cantrell
	  (reports 34101829, 34102877, 34457224)
	Also includes code and tests for Filter object and code stub for
	  testing translate with Filter object, but translate not yet ported to
	  Filter object

1.13_03 2013-09-17
	Another debugging release to track down FAILs seen by David Cantrell
	  (reports 34101829, 34102877, 34457224)
	Also includes documentation for new translate filters

1.13_02 2013-09-15
	This is a debugging release to track down FAILs seen by David Cantrell
	  (reports 34101829, 34102877)	

1.13_01 2013-09-02
	New features
	- 'check_contents' method - checks whether explict Masters contain all
	  ids in the underlying MapTables
        Bug fixes
        - 'apostrophe' bug: ID containing apostrophe triggered bug in partial
	  duplicate removal
	Test changes
	- Added test for schema mechanics
	Documentation changes
	- Deprecated obsolete workflow-related attributes and removed them from
	  examples
	- Deprecated obsolete maptable header macro - it was just a bad idea...
----------
1.12    2013-07-31
	Bug fixes
	- Fixed partial duplicates bug in which translate returned rows that 
	  were identical on all non-null columns, differing only in that one row
	  had nulls where the other had a real value
	Test changes
	- Cleaned up tests to improve CPAN install speed
	- Changed the scheme for telling CPAN that it's futile to run the tests
	  because MySQL is not accessible. I now check key requirements in a 
	  test script and skip out of the test suite if the requirements are not
	  met.  The main requirement that I check is that MySQL be accessible.
	  The test suite reports PASS in this case!! It would be far better to
	  eport NA or UNKNOWN, but I don't know how to do this robustly.
----------
1.11    2013-06-18
	New features
	- can specify history in IdType, rather than just in Master
	- new 'show_schema_graph' method
	Bug fixes
	- in 'validate', check for unmatched ids has to be case insensitive 
	  because MySQL does case intensive comparisons, e.g., searching for 
	  'htt' as gene_symbol
    	- detect isolated IdTypes, ie, IdTypes not contained in any MapTable.
          previously, load_implicit_masters would generate illegal empty query
----------
1.10	2012-12-02
	New features
	* new 'translate' options
	  - filters
	  - count
	  - validate
	* new methods
	  - load_implicit_masters
	  - count
	  - validate
	* histories
	    Master tables can hold old and current values for ids. translate,
	    count, validate use old values if they exist
	Bug fixes
	- 'translate' with empty input_ids. was generating illegal SQL, now
	  returns empty table
	- examples/babel.pl used deprecated qw(...) as parentheses. should have
	  been fixed in 1.02.  sorry	
	- 'translate' with empty input_ids would sometimes return NULL id
	- lingering bug in 098.example. test was calling example script with
	  wrong Perl interpreter and without -Mblib. thanks to CPAN smoke 
	  testers for finding this bug!!
----------
1.03    2012-08-21
	Added test for version number in POD
	Removed redundant 'dist_version_from' param from Build.PL

        Changed tests to correct deprecated use of qw(...) as parentheses

1.01    2011-01-22
        Added 'translate all' (more precisely, the input_ids_all option to
	  translate) to generate a complete mapping of the input type to the
          output types.

        First CPAN version, released on an unsuspecting world.

1.00_03 2010-11-19

	Added view operations to chk_mysql in Build.PL on the theory that FAILs 
	  are due to inability to create views

	Added Class::AutoDB to requires

0.90    2010-08-22
