a row. Commiting for backup purposes.

Reformatted getNonZeroRowLength to pass on the device Type in string and thus enable the lambda in SparseRow_impl.h

The x and b vectors might have different type.

- base class with non-virtual destructor causes undefined behaviour
- missing return statements at the end of non-void functions
- missing const before char* function argument
- reordered initialization of class members
- misleading indentation after for statement
- fixed use of uninitialized variables
- fixed unsequenced modification and access to variables (the C++
  standard does not define the evaluation order of operands, so
  expressions with side-effects such as j++ cause undefined behaviour)

	Seriove
	jen 2D
	používá pomalé operace: pass to MIC, free from MIC

Dále asi nepujde zkompilovat celé TNL, kvuli __cuda_callable__ == __device_callable__ a nezakrytí MIC částí kódu pomocí HAVE_MIC.
