TODO:

• START_GLOBAL_TIMER(tag) - this calls the start_timer, which creates local timer on the correct place in the hierarchy, further this timer is added to the list of global timers, this contains groups of timers with same tag, and collect/sum data from these timers in the report.
• Allow output even during calculation (not complete, but at least some thing) Report should contain time of start as well as time of creation of the report or time from start of the program.
• When generating report we has to deal with possibly different trees at every MPI process.
• test memory profiling in our own new and xmalloc functions - register allocatied and deallocated memory to active Profiler frame.
• test in parallel

• extended output: cas na jedno volani (jina redukce nez pro kumulativni cas, pokud je pocet volani ruzny) procenta vuci predkovi code point (az nekde na konci radky)

  !!! Unfortunately using constexpr is worse (without optimization). This is probably due to use of static variable for CodePoint, the access could be slow, and computation of hash is done only once. Actually timing results are:

  OPTIONS OVERHEAD (compared to call 2x clock()) -g, no c++11 : 18% -g, c++11 : 60% -O3,no c++11 : 6% -O3, c++11 : 6%
