#	 /+====================+\
#	 ||   Pretty clear !   ||
#	 \+====================+/
#
# Clear the screen and add a header at the top
# Header that you can customise with options
#
#
# By default, it does :
#	- Clean the console
#	- put a ls -l as header at the top
#
#
# There are optional arguments :
#
#	- -l : a lighter header
#	- -a : a heavier header with more informations, takes priority over -l
#	- -m : execute a make after the pretty clear, when working in C/C++ for example
#	- -g : show you the branches and status of the current git repository
