Removed base_aco.*
Added base_tsp.*
Changed aco.*, knapsack.* and tsp.* : renamed base_aco to base_tsp

Added base_tsp to problems.h
Added base_tsp to CmakeLists.txt
Merge remote-tracking branch 'upstream/development'
Added tsplib.py module, parses a TSPLIB file and returns an adjacency matrix.
Added small TSPLIB sample file, burma14.xml
Small changes and code tidy up in rest of files.
Fixed import problems with inconsistent XML tsplib files.
Renamed tsplib.py to tsp.py
Added tsp to __all__ in __init__.py from util folder.
(can do now: from PyGMO.util import *)
Added tsp.py to cmakelists install file.
Commented out knapsack and aco from everywhere necessary to be able to make
(only references to algorithms.h and problems.h and tests + wrappers)
Made some changes to base_tsp and tsp, added headers for BGL and defined graph type.
Removed knapsack and aco from cmakelists
getters and setters for base_tsp
tsp basic setup
Finished with base_tsp class
Finished constructors for the tsp class
Working on tests for the getters and setters (tsp)
Added function to get number of vertices for sparse 2D vector (matrix)
Wrote human readable extra function for tsp to output edge weights (costs)
Added random matrix test for best_solutions_test.cpp - now it passes test
Minor change in comment for base_tsp.h function
Fixed warning of comparing int with unsigned int in get_no_vertices
made vector2D_to_graph not const since it changes m_graph
Added serialization test lines
Moved typedefs to base_tsp.h.
Rewrote conversion function from vector2d to graph.
Changed default constructor in tsp.cpp
Wrote wrapper for graph adjacency list. not used yet (if ever)
Fixed comments for the vector2d to graph function
Added test_tsp.cpp generating random vector, instantiating tsp object,
converting it to a tsp graph, getting the graph and converting it back
to a 2d vector and checking if it is equal to the initial random matrix.
Finished human_readable_extra
Made conversion functions and get_no_vertices static and public.
Renamed conversion methods, added convert_ prefix.
Changed signature of graph_to_vector, now it's return by argument.
Also changed test_tsp to reflect changes.
Added vector2D m_weights member to tsp.
Wrote the objective function objfun_impl for tsp.
