[2.0] DDC-186 - Fixed SchemaTool indexes behaviour, changed a functional/integration model to use one index for test-coverage.

[2.0] DDC-169 - Changed AbstractPlatform and AbstractSchemaManager and children to accept Table, Index and ForeignKey instances for the respective create*() methods.

[2.0] DDC-169 - Finalized implementation of Schema diff algorithm, added diffs of sequences and foreign keys. Fixed several bugs and changed the API of the Schema objects.

[2.0] - DDC-169 - Fixed another regression in refactored SchemaTool, began porting of eZ Components Database Schema Comparator, SchemaDiff and TableDiff.

[2.0] - DDC-169 - Refactored lots of sections with duplicate code in gather relations part of SchemaTool::getCreateSql()

[2.0] - DDC-169 - Completed refactoring of SchemaTool::getCreateSql() to use new DBAL Schema API, several internal optimizations in SchemaTool are now possible. Stripped out shared functionality with getUpdateSql() so that this part of SchemaTool is still completly working with the old API.

[2.0] DDC-169 - Savepoint for Refactorings in Schema-Tool - It is now generating DDL according to the old and the new mechanisms in parallel. Equality of generation has been verified on Sqlite, Mysql, Oracle. If Postgres is also verified, the old code will be removed in favour of the new one completly.

[2.0] DDC-109 - Fixed another warning in SchemaTool with inverse join columns and unique constraints.

[2.0] DDC-114 - Extend SchemaTool Drop functionality to optionally drop the complete database. Additionally a filter against all existing table is applied to avoid errors due to dropping non-existant tables. Updated Schema-Tool CLI command with optional calls --drop=database --drop=metadata but kept original --drop which defaults to "metadata". Updated documentation.

[2.0] Fixed DDC-103 - Platform::getAlterTableSql() should return an array on all platforms, added doc-blocks on all methods and fixed some.

[2.0] Fixed DDC-101, DDC-102 - Ensure defaults for string length and field nullability are handled consistently in both update and create schema commands of SchemaTool.

[2.0] DDC-84 - Add Mysql Platform unittests for incremental changes of the metadata for the schematool update function. Fixed some quirks in the Unit-Test suite alongside, Fixed changes of length in SchemaTool update.

[2.0] Some work over SchemaTool update of schema (affects directly the CLI schema-tool task on --update option.

[2.0] Work on CLI: Added SchemaToolTask with preliminary support for dropping/creating the database schema. Prepared the sandbox. Adjusted build to include the sandbox.

[2.0] Refactored pieces of QueryBuilder, it does not use string concatenation anymore. Splitted from into from and join, allowing update and delete DQLs to be correctly built. Added missing entry set. Removed Expr\Having because it was useless. Updated docs.

[2.0] Applied fixes for character casing issues. Simplified inheritance mapping and improved handling of outer joins in Class Table Inheritance.

[2.0] Removed AssociationMappings from ResultSetMapping  for improved caching. Fixed caching issue with reflection classes and properties. Reimplemented and leaned up broken identifier quoting. Added support for named (native) queries. Fixed small hydration memory leak.

[2.0] Accomodate joincolumn names in the metadata, in the selection and the hydration processes. Improved Api of the ProxyFactory. Working implementation of lazy loading for *-to-one associations (affects #2348)
