 /** The initial quest for this APIFest is to create an API for boolean 

  * circuits. Such API shall be able to compose a boolean circuit from

  * basic elements and evaluate the result given initial values for 

  * input variables.

  * <p>

  * The basic elements include:

  * <ul>

  *   <li>negation - has one input and one output and changes 0 on input to 

  *          on output 1 and 1 to 0

  *   <li>and - has two inputs and one output. The output is 1 only if both 

  *          inputs are 1, otherwise it is 0

  *   <li>or - has two inputs and one output. The output is 1 always, 

  *          except in the case when both inputs are 0

  * </ul>

  *

  * <p>

  * The boolean circuit can be used to represent boolean formulas and 

  * compute the results for certain values of its inputs. The individual

  * tasks described as tests bellow.

  *
