ADD test: check mat_op_vec with 4-dimensional src and v for every axis
FIX documentation of matrix_op_vec
FIX remove fortran dependency (was cmake-cblas bug once?)
FIX name (and make cmake-confable) cuda architecture
ENH add 'sparse' connectivity version of Alex' convolutions
ENH make the if in cuvAssert "unlikely" to fail using gcc builtin
ENH add test for sparse connectivity convolutions
changed log1p of functors.hpp.
The math function log1pf calculates the same op and is optimized bedder.

ENH add Benedikt's custom allocator functionality to cuv tensor
FIX compilation errors induced by switch to benedikt's allocator-based version
FIX backport allocator test from c++11
ENH add more allocator tests
FIX and accelerate 2d copying and contiguency tests
FIX remove obsolete accessors.hpp
FIX serialization after changes due to benedikt's allocators
FIX remove assert preventing copy to view
FIX resize test, failed due to reallocation at same ptr
FIX default ctor of memory should construct allocator
FIX remove signed/unsigned warning
FIX use thread pool class in alloc test

the original implementation did not always work,
reusing a thread pool seems to be tricky.

the new implementation destroys the thread_group
after every loop by joining it (and thereby making
sure all tasks are done)
