RandomForest def predictRFStat(rf, X, statDictionary,n_jobs) optimization (memory and CPU) about rootinteractive HOT 2 OPEN

Start with predictRFStatPar so we can compare it with the previous version and later replace it ...

Benchmark:

• CPU time
• Memory
• results

from rootinteractive.

To save memory the predictRFStat should be optionally split to the chunk
If we consider that to be a function responsibility of the function - new parameter maxRows to be added

If maxRow is set then the function will be called in chunks with maxRows and all data will be merged at the end.

Memory consumption - nRowsxnTrees which can be significantly smaller than current nEntries x nTrees
