Description
-----------
The Pushd / Popd commands act the same way that they do in bash.
A stack of directories is created on the first pushd command.  
Every time a new pushd command is issued, it adds to the stack.
When a popd command is issued, the front of the stack gets popped
off the directory is changed into that dir.  

Pushd works like cd but saves a copy to the stack.
Popd will cd to the last element on the stack.

How to Run
----------
Pushd:
    pushd [directory] 
Popd:
    popd
