rename the directory `Network' to `HaskellNet'
On HaskellNet, I renamed the directory `Network' to `HaskellNet' because of conflict of the module name. HaskellNet already contains HTTP modules such as Network.HTTP, Network.Stream, and Network.TCP. However, ghc does not allow for two other packages to have a module of same name. You cannot build haskellnet if you have already installed HTTP, and vice versa.
