Recumulate

A useful variation is the Recumulate function, which resets the total to zero at selected points. This usage is: 

Recumulate(x,b,I)

where b is an array of booleans indexed by I, having 1 at each point where the cumulation is to be reset to zero. Recumulate is implemented as a User-Defined Function in the example Recumulate example.ana. A clever usage of this function computes the number of time steps that the system has been in the same state (see the example).
