This project is an interactive filter for pipes that enumerates stdin, and lets you pick the lines that go to stdout.

Currently these features are supported:
- Support multiple selections with comma separated syntax
  ex.
  Selection: 5,3,0
  Line5
  Line3
  Line0

- Support multiple selections appended to one another with '+' separated syntax.
  ex.
  Selection: 5 + 3 + 0
  Line5 Line3 Line0

- Support an "a" as a selection for all, which just spits out the list (only the number enumerated)
  At this point it would basically be like "head -nNUM"
  The difference is that you got so see what it was sending through first, and optionally decide to send only part, or 
  nothing at all

- Support use of NUL instead of newline as input/output item delimiter
  This is useful with input/output data that can include '\n'.
  Use -0 to turn this on.

- Escape some characters
  This is on by default.  Use -r to turn it off.
  (It is also forcibly turned off by -0.)
