The splitting with if( std::is_same<...> ) is not perfect, the code for
all devices was always visible to the compiler, and irrelevant parts
were optimized out at a much later stage. To fix compilation for MIC and
custom data type, we need proper template specializations.

Doing this in a destructor is the only place where we can guarantee that
no open file descriptors will be left behind.

Neurčity stav, kdy  bylo hotové tnlArray a začal jsem pracovat na tnlvector, ale zjistil jsemm, že nejde přeložit znovu celý projekt. toto je jen záloha pro návrat.

Implemeting heat equation benchmark.

Adding simple heat equation benchmark for CUDA.

Problem with marking tnlObject's virtual destructor as __cuda_callable__
is yet to be solved...
