Small compression improvements

Slightly better distribution properties
Minor init efficiency (cheap storage trick)
More compact header (Opportunistic Bit Carry)
Note : this version is incompatibles with previous ones
Improved 32-bits FSE decompression speed
Modified experimental detailed API

Improved speed of 32-bits version
Variable bitStream sizes
and accidental automatic reformating ...
Update link to Jarek Duda document
Used large bit Container to improve compression speed
fix : end of segment
Small compression speed improvement
Readme : report the compression speed improvement
Merge pull request #6 from Cyan4973/beta

Beta
memory usage can be dynamically selected

use memLog
use new capability to select memLog within tests

-l uses memLog=10 for rl,ml,of & lb datasets
Adapt tests

variable memlog sizes within -l tests
