• ...

In 0.7

Amount of changes for Silme 0.7. We may want to incorporate some of those patterns for format/io in Silme 0.8.

• silme.core.Entity.get_value() -> silme.core.Entity.value
• silme.core.Entity.get_value('ab') -> silme.core.Entity['ab']
• silme.core.Entity.set_value('foo','ab') -> silme.core.Entity['ab'] = 'foo'
• silme.core.Entity.remove_value('ab') -> del silme.core.Entity['ab']
• silme.core.Entity.remove_value() -> del silme.core.Entity.value
• silme.core.EntityList.get_entity('id') -> silme.core.EntityList['id']

(in above cases all get_value, set_value, remove_value still work, but the new syntax should be more handy)
