[GSOC] Persistent Data Structures detailed information

[Jay]

Hello, My name is Jay Rajput.

In Persistent Data Structures, I am planning to implement DS 
algos for lists, sets, trees,etc.. Should these data structures 
store elements of different data types at the same time? ( like 
python)
eg: list=['hello',123,67,98]

Also, it would be really helpful if someone can brief me about 
the pre-requisites. I have implemented all the data Structures in 
C, also I have taken courses in Advanced Algorithms and 
Functional Programming.

Thanks,
Jay Rajput
