+//  [ CRYSTAL SHELL ]
+//  the purpose of this module is to provide a basic unix shell like experience for the user
+//  to interact with the OS
+//  this is a rewrite of my original shell.
+//  this shell should support:
+//  - browsing the virtual filesystem
+//  - executing programs
+//  - basic arithmetic
+//  - chained execution ( multiple commands linked together) eg: '5 + 5 | echo' which calculates
+//    the result of 5 + 5 and then sends the result to an echo command which prints it to console
