in_place_ policy is  tied to linalg
nt2/options.hpp is now automatically aggregated
Cleared out gammainc related options

Those options where actually internal only
Reworked and completed freqspace
Move tags to sdk instead of placeholders
use if(TARGET) to test if target exists instead of searching for a property
Correct ulp problems with sne
work around weird bug with visual studio 2012 by using mpl::and_ instead of &&
additional digits (taken from matlab) added to reference answer in mnorm test because of test failure in double precision
gather_avx unit test moved to gather.cpp in the main repo
Fix #783 - Narrowing in storage_size settings

storage_settings of dynamic size was set to -1, leading to a
narrowing error in C++11. As this default value is purely
informative, it has been set to 0ULL instead. Associated
assertion has been modified to comply with this new semantic.
Moreover, unit tests were amended to compare to 0ULL instead of -1.
warning fix in mnorm + fix precision threshold in orth test
adapt ulp threshold in gelsy unit test
use absolute difference to compute precision in sne unit test
reduce tested accuracy of sne in test
Merge pull request #785 from MetaScale/sne_absdiff

Use absolute difference to test accuracy of sne instead of ulps
is_complex works for const also
correct sne error for mini-titan
