 * Explanation: This is a recursive descent parser implemented using JavaCC for 
 *              the parser generator and for lexical analysis.
 *
 * EBNF form:
 * S := VARIABLE '=' S | E | EVAL VARIABLE
 * E := ( '+' | '-' ) E T | T
 * T := ( '*' | '/' ) T F | F
 * F := EXP '(' F G ')'
 * G := VARIABLE | DOUBLE | '(' E ')' | ('arc')? TRIG '(' E ')'
 * TRIG := 'cos' | 'sin' | 'tan'
 * EVAL := 'eval'
