public FunctionEvaluator bind(String name, double value) {
        return bind(name, Tensor.Builder.of(TensorType.empty).cell(value).build());
    }
Binds the given variable referred in this expression to the given value.
This is equivalent to <code>bind(name, Tensor.Builder.of(TensorType.empty).cell(value).build())</code>

@param name the variable to bind
@param value the value this becomes bound to
@return this for chaining
