1.9.0

• 117:
  Changes and fixes in Brain Python module:
  • Functions that take gids now preserve the iteration order of the input in
    the output arrays/lists.
  • Replaced Python sets with numpy arrays in functions returning GID sets.
  • Circuit::getXYZNames functions renamed to Circuit::getXYZTypeNames.
• 113:
  Support for old circuits containing only synapse center positions.
• 110:
  Break PersistentMap out into keyv::Map
• 107:
  Added Sphinx generated documentation of the brain python module.
• 102:
  Use PersistentMap for caching synapse positions loaded from brain::Circuit
• 94:
  Fixed SWC morphology parser for morphologies with soma contour. The parser was
  creating invalid soma sections when the first order sections where connected
  to arbitrary soma sample points.
• 89:
  Python wrapping of brain classes.
• 88:
  • Brain namespace enums made strongly typed.
  • Fix for brain::Section::getSamples for sections where the first point
    appears repeated.
• 85:
  Implement brain synapses specification
• 84:
  Brain synapses specification
• 83:
  Add brain::Circuit::getRandomGIDs()
• 82:
  Improve performance when reading synapse attributes from non-merged files
• 81:
  Fix GID out-of-bounds handling for MVD3 in brain::Circuit
• 79:
  Use PersistentMap for cache in brain::Circuit::loadMorphologies(); add thread
  safety w/ synapses cache
