We sometimes want to use trees in ROME.

One way is to read it by TSocket connection. But treees are larger than histograms in general, and it 
takes time to download. 
 And I need to make shared library when I changed the structure of folders.

So, I want to propose is to prepare Cint mode with continueing analysis in background.

Currently, when user press "i", ROME stops analysis and goes into cint mode. This is good for offline 
mode, but this is not good for online mode. So I propose that when user press "I", ROME goes cint 
mode, and continue analysis in background.

Then we can see Trees at run time.

In addition, If you are going to implement this feature, please prepare short way to call trees in cint mode.
If I understand correctly, the way to call a tree is like,
gAnalyzer->GetTreeObjectAt(0)->GetTree()->Draw("");
but it is too long to use in interactively and we need to remeber the number of trees.
gAnalyzer->GetTree("trigger")->Draw();  is better.
