## Function: trap_push 'COMMAND_STRING'
|
|
## Appends a command to a trap, which is needed because default trap behavior is to replace
|
|
## previous trap for the same signal
|
|
## - 1st arg: code to add

## - ref: http://stackoverflow.com/questions/3338030/multiple-bash-traps-for-the-same-signal

|

## Print message to stderr

## Function: die MESSAGE
|
|
## Print message to stderr and exit the whole process
|
|
## Note:
|
|
## Using () makes the command inside them run in a sub-shell and calling a exit from there
|
|
## causes you to exit the sub-shell and not your original shell, hence execution continues in
|
|
## your original shell. To overcome this use { }
