Interactive command line utility which uses the Java at_client library

To see usage:

java -jar target/at_shell-0.0.1-SNAPSHOT.jar

To run shell against virtual env as @gary:

java -jar target/at_shell-0.0.1-SNAPSHOT.jar vip.ve.atsign.zone:64 @gary

Note: This will default to looking in $HOME/.atsign for AtKeys.

To point to the at_demo_data package keys:

java -DATSIGN_KEYS_DIR=target/at_demo_data/lib/assets/atkeys \
  -DATSIGN_KEYS_SUFFIX=.atKeys \
  -jar target/at_shell-0.0.1-SNAPSHOT.jar vip.ve.atsign.zone:64 @gary

Note: JDK 9+ has stricter JAR verification for cryptographic providers. This means that BouncyCastle cannot be included in the shaded jar (this would remove the signature). The maven build downloads the bouncycastle jar to target/lib and include this in the jar manifest classpath. If you copy the FAT jar elsewhere you need to ensure that lib dir, containing the bouncycastle jar is also copied too.
