Some refactoring, make all operations handle inplace reductions.
In Layout, expose attribute spacing, layout_center, layout_angle, layout_xreflection, layout_yreflection.
Allow unpacked special attributes to be set.
Remove autoscale keyword in plot method. Make sure transform has no side effects.
Use vertices to compute centers.
Enforce attribute 'removed' to be an array of the layout's shape.
Make Pointing a general purpose class. Add PointingEquatorial, PointingScanEquatorial and PointingHorizontal.
Add binary rule to ensure that CartesianGalactic2EquatorialOperator and CartesianEquatorial2GalacticOperator are undertood as inverses.
Update CartesianEquatorial2HorizontalOperator and CartesianHorizontal2EquatorialOperator to use PyOperators 0.9's DenseBlockColumnOperator and DenseBlockDiagonalOperator.
Implement operators SphericalEquatorial2GalacticOperator, SphericalGalactic2EquatorialOperator, SphericalEquatorial2HorizontalOperator and SphericalHorizontal2EquatorialOperator.
Lazy loading of interface modules.
GCC 4.5 compatibility fix.
Numpy 1.7 fix.
Add binary rule to ensure that Healpix2{Cartesian|Spherical}Operator and {Cartesian|Spherical}2HealpixOperator are understood as inverses.
Implement ProjectionOperator, using sparse matrix types FSRMatrix and FSRRotation3dMatrix.
Don't exclude indices after a negative one.
Some docstrings.
Implement 'canonical_basis_in_kernel' method in ProjectionOperator.
Implement ProjectionOperator 'restrict' method.
Make HealpixConvolutionGaussianOperator handle polarized maps.
