Cubes 0.7.1 released

I am glad to announce new minor release of Cubes - Light Weight Python OLAP framework for multidimensional data aggregation and browsing. The news, changes and fixes are:

New Features

• New method: Dimension.attribute_reference: returns full reference to an attribute
• str(cut) will now return constructed string representation of a cut as it can be used by Slicer

Slicer server:

• added /locales to slicer
• added locales key in /model request
• added Access-Control-Allow-Origin for JS/jQuery

Changes

• Allow dimensions in cube to be a list, noy only a dictionary (internally it is ordered dictionary)
• Allow cubes in model to be a list, noy only a dictionary (internally it is ordered dictionary)

Slicer server:

• slicer does not require default cube to be specified: if no cube is in the request then try default from config or get first from model

Fixes

• Slicer not serves right localization regardless of what localization was used first after server was launched (changed model localization copy to be deepcopy (as it should be))
• Fixes some remnants that used old Cell.foo based browsing to Browser.foo(cell, ...) only browsing
• fixed model localization issues; once localized, original locale was not available
• Do not try to add locale if not specified. Fixes #11: https://github.com/Stiivi/cubes/issues/11
