zxc 0.1.0

`zxc` allows you to quickly perform a few common opperations on STDIN, for example: ``` $ echo $PATH | zxc split : split / present print ``` The command chain above will 1. get the list of directories in your `$PATH`, 2. split it into a list, using ":" as a delimiter, 3. split each element of said list into a sublist, using "/" as a delimiter, 4. remove empty elements, 5. print every element of every sublist. This works by generating a tree, where each node contains text, and exposing "steps" to the user, which are procedures over said tree, In the example above, "split", "present" and "print" are steps, the first one taking arguments. Use `zxc -H` to read a manual listing available steps.
