13 TODO:
14 Have separate names for the wrapper classes in the cases of: [done]
15 clones/non clones
16 split/non split
17 split levels
18
19 Have a solution for passing top+"."+middle to the parents classes [probably done .. need testing]
20
21 Have a solution for the return by references of abstract classes [not done]
22
23 Have object inside ClonesArray properly treated! [done]
24 Why is there 2 TRef proxy classes? [done]
25
26 check why some inheritance are TObjProxy and not TPx_
27
28 Be smart enough to avoid issue about having 2 classes one unrolled and one non unrolled!
29
30 When using in interpreted mode understand why the reloading reloads the calling script and then crashes :(
31
32 CINT does not properly call the custom operators when doing return fNtrack.
33
34 CINT does not handle fMatrix[2][1] well.
35
36 The user's function in script.h are not exposed by ACLiC.
37
38 Review the method to avoid the useless refreshing of the generated file
39 - for most efficiency it would require a different name for each tree
