c8cbc1665e enhancements of the plot generator: 
- removed the ugly X11 and PNG gnuplots terminals
- use enhanced postscript terminal
- use imagemagick to generate the png files (with compression)
- disable the fortran impl by default since it is as meaningless as a "C impl"
- update line settings

99a625243f Optimization: added super efficient rowmajor * vector product (and vector * colmajor). 
It basically performs 4 dot products at once reducing loads of the vector and improving
instructions scheduling. With 3 cache friendly algorithms, we now handle all product
configurations with outstanding perf for large matrices.

8233de8b69 various minor updates in the benchmark suite like non inlining 
of some functions as well as the experimental C code used to design
efficient eigen's matrix vector products.

in the benchmark suite

7b4c6b8862 in BTL: a specific bench/action can be selected at runtime, e.g.: 
BTL_CONFIG="-a ata" ctest -V -R eigen
  run the all benchmarks having "ata" in their name for all
  libraries matching the regexp "eigen"

28539e7597 imported a reworked version of BTL (Benchmark for Templated Libraries). 
the modifications to initial code follow:
* changed build system from plain makefiles to cmake
* added eigen2 (4 versions: vec/novec and fixed/dynamic), GMM++, MTL4 interfaces
* added "transposed matrix * vector" product action
* updated blitz interface to use condensed products instead of hand coded loops
* removed some deprecated interfaces
* changed default storage order to column major for all libraries
* new generic bench timer strategy which is supposed to be more accurate
* various code clean-up
