                        SnapshotUtils.java DefaultSnapshotResolver.java
                        SnapshotResolver.java
  Log:
  Early version of snapshot resolver. I would like to use .snapshot-version file 
locally and remotly for keeping time stamps.

  This will allow to use any local repository also as remote repository for other 
people but first of all release plugin will be able to use local .snapshot-version 
files while release will be made
