R: fixed a typo in the manual. Thanks to Stephen Haptonstahl for reporting it, see issue #503.
R: add.edges does not allow now zeros in the vertex set. Fixes issue #503, thanks to Stephen Haptonstahl for reporting it.
some C99 quirks fixed in lad.c; more to come
cleaned up igraph_i_lad_updateMatching as well
Updated ignore file.
fixed a memory leak in igraph_get_shortest_paths2.c
more fixes to the LAD isomorphism algorithm to make it C89-compliant
Remove AM_EXTRA_RECURSIVE_TARGETS from configure.ac, it requires a recent version of automake. Fixes issue #499.
Added bench.h and a simple benchmark for transitivity.
Merge branch 'develop' into 0.7-graphlets
Use integer vectors in local transitivity calculation, wherever easily possible.
Added an R regression test for transitivity.
Speed up local transitivity calculation, do not store vertices that do not match the rank ordering.
Added printf functions for igraph_vector_t and igraph_matrix_t.
LAD compiler issues mostly fixed; also, better error handling was implemented
Replaced the C++ benchmark code with C code, and measure processor time instead of real time.
Merge branch '0.7-benchmarks' into develop
Separating out the triangle (transitivity) code into a different file.
LAD isomorphism search fixed to actually compile in MSVC
Merge branch 'feature-fix-lad-msvc' into develop
