Makefile

#  Makefile for using flex with bison 
#  
#  The executable receives the name of the current folder
#      Do not use spaces in the name of the folder 
#  
#  The .lex and .y files used are the first ones found by ls 
#   
#  If there is a .txt file, it will be used as the input of the executable 
#  
#  This Makefile works on Linux and on OSX
