Added config file for csh/tcsh. It is based on the 'bash_profile' file, but with several differences:  * Default ONOS_ROOT value is $HOME/onos instead of $HOME/onos-next  * Convenience utility functions and aliases are not included  * $MAVEN/bin is not included in the executable path  * The 'cell' funcion from BASH is renamed to 'onos-setup-cell'    Also, 'onos-setup-cell' always requires an argument: the cell name    Displaying the current cell setup can be done by the   'onos-show-cell' script
