Completed PATH searching.
Can execute commands by way of searching the PATH environment variable.
Have yet to test if it works with connectors and redirection.
Tested new method of command execution using connectors.
The ; connector works as it should.
The || connector does not work properly and instead works like
    the ; connector.
The && connector works as it should.
Fixed the bug where the || connector wasn't working properly
Fixed the undefined behavior bug when multiple connectors are used.
Program executes the first command and if there is a different connector
	after it an error will be yielded and the prompt will pop up
	again.
Updated the README file.
Implemented a basic form of the cd command.
The command can go back to the home directory if no arguments are
    passed to it.
Have yet to test going back to home directory via the ~ and multiple
     destinations.
Going into other directories does not work.
The prompt now displays the current directory.
Completed implementation of the cd command.
The program will jump to a valid location if it is the only one
    given.
The program can handle cd used with connectors.
The program will yield undefined behavior if used with piping or
    redirection.
Updated README
Program is able to catch the ^C signal.
Updated the README file as well.
