/**
 * This program should accept two parameters on the command, a file to copy
 * from and a file to copy to.  Instead of opening and copying the files itself
 * it should create a pipe between the 'from' and 'to' programs to do the
 * copying.  I.e. 'copy source dest' should be the same as typing in the shell:
 * from source | to dest
 * This program should then a) Create a pipe, b) fork a new process, c) exec
 * the from and to programs in their respective processes after redirecting
 * their stdin/stdout to/from the appropriate pipe descriptors.
 * Hint: Remember to close both pipe descriptors in each process after
 *       duplicating them.
