    METRON-1037 Added POWER function

    ## Contributor Comments
    
    This is a quick addition to the Math functions. It may be worth revising following the work @cestella did this morning to add a more general implementation on top of #650 
    
    I will probably add 2 argument capabilities and port this work to #650 when it's in once that is in.
