new mental-model in the CLI

[imaman]

bigband ls p1   # Show all instruments in the p1 package

bigband ls p1-p2  # Show all instruments in the p1-p2 package

bigband ls p1-p2-p3-myLambda  # shows resources available for bigband cat. Sepcfically: log file, info

bigband cat p1-p2-p3-myLambda/log
bigband cat p1-p2-p3-myLambda/info

bigband exec p1-p2-p3-myLambda '{"a": 1, "b": 2}'

Alternatively, perhaps the command "ls", "cat", "exec" is an extension to the last component in the path (with the default being "ls"), so that one can do:

bigband p1-p2-p3
bigband p1-p2-p3-myLambda 
bigband p1-p2-p3-myLambda.exec '{"a": 1, "b": 2}'
bigband p1-p2-p3-myLambda.log
bigband p1-p2-p3-myLambda.info

this results in even shorter command lines but it may be confusing to newcomers.
