```
class PickleReader
extends Object
```
generic Python Pickle file reader only utilizing records needed for PyMOL. It appears we must read integers littleEndian and doubles bigEndian. 2013.04.06 -- added memo functions. PyMOL pickling is using LONG_BINPUT way too often. This results in a huge unnecessary memory overhead. My only solution is to only cache Strings in memo, and then only selectively -- not parts of movie; not when markCount > 5 (residues). This seems to work, but it is still way overkill, since each atom generates several items. see http://www.picklingtools.com/
