    An equation specification file is used to define
the relationships between your variables. In order
for the program to understand these relationships,
these equations must be specified in a formal
manner.
    The Grammar for the input syntax of the
language is as follows:

    statement:    /* empty */
        | statements statement
        ;

    statement: VAR_NAME = expression
        | 'precision' = NUMBER
        | ';'
        ;

    expression:    VAR_NAME
        |    NUMBER
        |    PI
        |    expression + expression
        |    expression - expression
        |    expression * expression
        |    expression / expression
        |    expression % expression
        |    expression ^ expression
        |    - expression
        |    sin( expression )
        |    cos( expression )
        |    tan( expression )
        |    exp( expression )
        |    log( expression )
        |    log10( expression )
        |    compound(expression, expression)
        |    annuity(expression, expression)
        |    arccos(expression)
        |    arcsin(expression)
        |    arctan(expression)
        |    ceiling(expression)
        |    cosh(expression)
        |    floor(expression)
        |    sinh(expression)
        |    sqrt(expression)
        |    tanh(expression)
        |    ( expression )
