v0.13.0

• New consistent use & documentation of the basic functionality:
  • All basic functions (e.g. up42.get_blocks) are accessible
    from the up42 import object. Now consistently documented in the up42
    object code reference.
  • The option to use this basic functionality from any lower level object will soon be
    removed (e.g. project.get_blocks, workflow.get_blocks). Now triggers a deprecation warning.
• The plotting functionality of each object is now documented directly in that object's code reference.
• Fix: Repair catalog search for sobloo.
• Various improvements to docs & code reference.
• Overhaul & simplify test fixtures.
• Split off viztools module from tools module.
