/* OGFForm jQuery plugin 
    OGF Controls register their validators with the containing form by jQuery("#fomrid").OGFForm("RegisterValidator", validator_func);
    You may check to see if the form is valid by the following FormIsValid = jQuery("#fomrid").OGFForm("IsValid");

    Other OGF controls will register themselves in the containing OGF form. When an OGF form is submitted it will call all the validators and return true/false.
    Each OGF control should display validation in real time (use Ajax if nessesary)
