      Disable internal bounds checking in property maps · 0ababf9c
      Tiago Peixoto authored
      This includes a new vector property map type (fast_vector_property_map)
      which has optional disabling of bounds checking, through its associate
      map type (unchecked_fast_vector_property_map). This should improve
      performance on algorithms which depend on tight loops which access
      property maps.
      
      Bounds checking is only disabled locally just before the algorithms run,
      and proper care is taken for bounds checking _beforehand_. The property
      maps exposed to python still have internal bounds checking.

      Add direct support for degree propery map creation · 8ae75c9f
      Tiago Peixoto authored
      i.e. g.degree_property_map("in") will create and return a vertex property map
      which corresponds to the in-degrees of the vertices. This is useful for
      temporarily modifying or getting an array of degrees.

      Add support for array access to property maps · e84aaf3c
      Tiago Peixoto authored
      A property map object has now a get_array() member which returns an internally
      owned array pointing to the property values.

      Several improvements to graph_draw() · e4d79af6
      Tiago Peixoto authored

      and a couple of bug fixes.

      Rewiring: bugfix, improvements and restructuring resulting in cleaner and faster code · b1e1bc5e
      Tiago Peixoto authored
      Restructure the rewiring code, introducing further abstraction through
      class inheritance.
      
      Both uncorrelated and correlated cases draw edges directly.
      This has actually proven faster than drawing vertices for the correlated
      case, since realizing that indexes could be stored instead of edges.
      Doing so avoids changes in the pool of candidate edges, which in turn
      removes the need to rebuild it for each edge to rewire.
      Consequently, it also makes the uncorrelated case a lot quicker.
      
      In the uncorrelated undirected case, the new code also fixes a serious
      bug: when building the edge pool, only one end of each edge was looked
      at, because the "edges" vector is not equivalent to drawing all
      out_edges from all vertices, as is done now.

      Add convenience module graph_tool.all · 16d85651
      Tiago Peixoto authored
      This allows to import all submodules from graph_tool with one command,
      e.g.,
      
         from graph_tool.all import *

      Makefiles: AM_CPPFLAGS use srcdir · 1c84328d
      Tiago Peixoto authored
      Add $(srcdir) to include paths in AM_CPPFLAGS so that we can
      compile the program writing all targets into a directory separate
      from the sources.
      This is done simply by creatig a subdirectory of the project root
      and running "../configure" and "make" inside it.

      Add dedicated average correlation calculation · 48aec77d
      Tiago Peixoto authored
      This is a re-implementation based on new histogram code, which does not
      build a 2D histogram, and is thus more exact and uses less memory.

      Fix edge indexing problem when modifying graph · dc184b46
      Tiago Peixoto authored
      This fixes a rather central bug, which causes duplicated indexes if
      edges are removed and then new ones are added. Edge indexes are now
      recycled as they are removed and then new ones are added. This still
      guarantees O(1) complexity when adding or removing edges.

      Add load_graph utility function · c804ff8e
      Tiago Peixoto authored
      Avoids having to do
      
          g = Graph()
          g.load("foo")
      
      each time. Now one can do simply,
      
          g = load_graph("foo")
      
      Fantastic.
