[AstroPy] Summer scholar

[Rene Breton]

Hi Joe,

That's an interesting suggestion and I just searched a bit and came 
across a scipy package called PyWavelets! Have you ever heard about it? 
I've never used it myself since last time I had to use wavelets stuff 
was a while ago, well before this came to existence.

It certainly seems to me that working on a PyWavelets sub-package as 
part of the AstroPy library would be a useless duplicate of effort unless...

I'd look into the next couple things:
1. Does PyWavelets have all the functionalities that one (you) is 
looking for? If so, problem solved. If not, maybe it would be a good 
idea to implement what's missing in that package in order to keeps 
things well organized, especially if the things you have in mind are 
general enough and not too specific to astronomers.
2. If needed, we could think about a specialized wavelets sub-package in 
AstroPy with that suits some very specific need of astronomers (not sure 
what it would be though). Again, to me the "requirement" would be to 
make it be some kind of front-end to PyWavelets. By doing things this 
way, we don't include further dependencies, which is certainly 
fundamental to AstroPy. If one wants to use the wavelets sub-package, 
then one can make sure that PyWavelets is working and that's all. But 
again, I think solution #1 would be better because it would avoid 
possible strong divergence in the future.
