Added Session
pretty much the same as before
Added Version utility
This class gives the ability to compare two versions like version_compare for php versions

examples:
Version::compare('1.0.1', '1.2.0'); -> 1
Version::compare('1.2.0', '1.0.1'); -> 0
Version::compare('1.2.0', '1.2.0'); -> -1
Version::compare('1.0.1', '1.2.0', '<') -> true
etc...
