Chrs

Updated to support ChRIS backend version 3.3.1 feature "piping titles" (backwards incompatible)

- The behavior of `chrs download` now works more like how the `cp` command works regarding how created files are named.
- When only a single file is given as the argument to `chrs upload` or `chrs download`, the progress bar will indicate the progress of the single upload (bytes uploaded instead of 1/1 files uploaded)

chrs tree --full` now shows the full path for both files and "folders"

Added a new command `chrs info` which shows you your current login information.

Fixed a bug with the `dircopy --dir` argument when running `chrs upload`
