Remove alembicManager, and other unused functions.

Simplify 'vertex cache' lookup logic.

Remove unused functions.

De-duplicate object name creation logic.

Cleanup.

AbcHairWriter: split write function in smaller ones.

Remove 'rotate_matrix' property from AbcObjectWriter.

Not needed anymore.

Cleanup: namespace usage.

Cleanup: style.

Replace hard coded axis conversion with UI parrameters.

Cleanup: remove some unused/outdated code.

Set up objects' position, rotation and scale upon import.

Object hierarchy is now restored upon import.

The algorithm isn't very efficient as it loops, for each object, over
all the objects in the scene.

A more straightforward way would be to build a tree from the Alembic
archive and use this for the actual object hierarchy, however every
attempt at this were unsuccessful. This is to be revisited in the
future.

Merge branch 'master' into alembic_basic_io

First attempt at restoring object hierarchy when importing a file.

Cleanup: unnecessary (left over) changes

Merge branch 'master' into alembic_basic_io

Cleanup: remove some unused functions.

Rewrite the import function to avoid traversing the archive for each
object type.

Instead of gathering the object names, make use of object readers
directly.

Pass the Alembic IObject to the reader in their constructor instead of
retraversing the archive everytime.
