Refactoring BCAE models

[YHRen]

• [x] split bcae.py into three files: blocks.py, bcae.py and cae.py
• [x] mv functions with name "block" into blocks.py, and remove get_ prefix.
• [x] mv CNNencoder and CNNDecoder and CNNAE (with single=True logic path) to cae.py
• [x] BCAE inheritates from CNNAE, and add the single=False logic path in __init__ and forward.
  • [x] BCAE implemented with blocks in blocks.py

Hi Ray, I found out that the code becomes more succinct and readable if when constructed BCAE anew from the blocks in blocks.py instead of making it an inherited class of CAE. So I am wondering whether can skip the inheritance part but make BCAE standalone.

Yes. Feel free to submit a PR and we can do a code review together.
