SQL-Interpolate-0.30

Changes for version 0.30 - 2005-01-10

General
Refactored SQL::Interpolate module into multiple modules. Everything except sql_interp-related functionality moved out of SQL::Interpolate and into DBIx::Interpolate, SQL::Interpolate::Filter, and SQL::Interpolate::Macro (new module). (recommended by mark s)
Reorganized macro processing. SQL::Interpolate contains only hooks for macro processing, and SQL::Interpolate::Macro implements various macros.
SQL::Interpolate
added sql_var type
added sql_literal type (thanks mark s)
("WHERE x in", []) now generates "WHERE 1" not "WHERE NULL"
croak not die
macros, sql_var, and sql_literal can now exist in elements of aggregates (hashref and arrayref)
DBIx::Interpolate
DBIx::Interpolate is now derived from SQL::Interpolate.
Support for statement handle sets (stx/prepare).
Renamed select_key() to key_field().
SQL::Interpolate::Macro
SQL::Interpolate::SQL is now a macro for uniformity.
new macros: relations, sql_and, sql_fragment, sql_if, sql_link, sql_or, sql_paren, sql_rel
removed limit() macro since MySQL supports Postgres syntax. (thanks mark s)
Other
reorganized POD (thanks mark s)
reorganized test cases
