This script performs various actions by default.

First it will create a ${LBL}bin${CLR} directory in your home folder (if one doesn't exist) 
and add it to your \$PATH variable (via ${CYN}.bash_profile${CLR} or ${CYN}.bashrc${CLR}).

It will then create a ${LBL}.templates${CLR} directory in your home folder with various
template files for use with ${GRN}new${CLR}. 

The ${GRN}new${CLR} command is added to ${LBL}${HOME}/bin${CLR} and is used to create a
new file based on a template within the above mentioned ${LBL}.templates${CLR} directory. 
It will then exit into your default editor. If no default editor is defined within your 
profile it will exit into vim or nano, whichever is found first (checked in that order).

You have five seconds to exit this script with ^c (CTRL + c)..."
