#   I actually use it as a part of my startup, so I am not really sure how to pack it, yet I wouldd like to contribute
#-------------------------------------------------------------------------------------------------------------------------------
#
#   How to use?
#-------------------------------------------------
#1)     Add desired paths to the cdpath variable
#2)     Use in your shell: $c [directory]
#2.5)   You *have to* use an argument. If you wish to simply $cd, use $cd command.
#3)     If the path exists, you will cd into the first match found (the command is iterating over the list in the correct order,
#   i.e. first element is being iterated overin the first place)
#3.5)   But if path does not exist, you will receive a proper echo.
