 USAGE
 EXECUTION OF THE PROGRAM IMMEDIATELY TRANSFERS CONTROL TO THE COMMANDLINE, ALTHOUGH NO INFORMATION WILL BE OUTPUT.
-ALL OPERATIONS REQUIRE A SPACE BETWEEN ALL OPERANDS AND OPERATIONS. FAILURE TO DO SO MAY RESULT IN MALFORMED OUTPUT.
 
 ALL COMMANDS MUST START WITH A VARIABLE, OPERAND, OR PARENTHESIS (NO OPERATIONS UNLESS TO INDICATE A NEGATION)
 I.E ans = 5

 COMMON ERRORS:
 ALL PARENTHESIS MUST BE CLOSED ELSE AN ERROR WILL BE PRODUCED. 
-ADDIITONALLY, THE INPUT MUST CONTAIN SOME TEXT.
 EACH LINE MUST CONTAIN A SINGLE ASSIGNMENT OPERATIONS, WITH THE ASSIGNMENT VARIABLE TO THE LEFT AND THE EXPRESSION TO THE RIGHT.
 ASSIGNMENT OPERATIONS MUST ONLY CONTAIN A VARIABLE ON THE LEFT, NO OPERATIONS ARE PERMITTED.
