GDL2, EOSQLQualifier Implementation

[Georg Fleischmann]

Hi,

here is my implementation of EOSQLQualifier.
EOExpressionArray seems to be an overkill here, but I just used the  
ivar as is.

* EOAccess/EOSQLQualifier:
        [EOSQLQualifier -initWithEntity:qualifierFormat:]
        [EOSQLQualifier -schemaBasedQualifierWithRootEntity:]
        [EOSQLQualifier -sqlStringForSQLExpression:]
        [EOSQLQualifier -dealloc]
        implemented

Best wishes,
Georg Fleischmann
