    genUID

Create a string which will be a suitable ID for an element. The ID will be unique (not currently in use by any other DOM element).

  
## annotated.js
function (
    p // an optional prefix for the id
)
{
    var c = 0, // c is the counter to add as a unique suffix to the end of the optional prefix string
    i; // i is the unique id string
    p = (typeof p==="string")?p:""; // if p is a string it can be used as the prefix, otherwise p is set to the empty string
    do {
        i = p + c++; // the id is set to the prefix joined with the incremented counter
    } while (document.getElementById(i)!==null); // if an element has been found with this ID we must loop again, incrementing the counter until a unique ID is created
    return i; // return the id string
}

## index.js
function (p) {var c = 0,i;p = (typeof p==="string")?p:"";do{i=p+c++;}while(document.getElementById(i)!==null);return i;}
