## Script to run APEX Applications, call with '-h' for help
## - requires BASH with associative arrays, bash of at least version 4
## - for BASH examples with arrays see for instance: http://www.artificialworlds.net/blog/2012/10/17/bash-associative-array-examples/
## - adding a new app means to add a command to APEX_APP_MAP and a description to APEX_APP_DESCR_MAP using same/unique key
