Saves (serializes) an object to disk.

Usage
qsave(x, file, compress_level)
Arguments
x

the object to serialize.

file

the file name/path.

compress_level

The compression level (-50 to 22). Default -1. Higher values tend to have a better compression ratio, while lower values/negative values tend to be quicker. Values with good compression/speed tradeoffs seem to be -1, 1 and 4.
