A unit of work is a simple storage with write lock/unlock. The manager/package now share a unit of work instance. The unit of work is used to prevent shared dependencies from being cloned/copied "at the same time" fixing issue #81. The prune and version resolving algorithm was also not correct. It now resolves versions correctly, fixing issue #57. - Fix I/O errors caused by copying/clone repos simultaneously to the same dest. - Optimize the clone/copy step by avoiding it if the last resolved resource is the same. - Fix failing test (at least on my windows machine) - Add some more tests - Fix CS.
