Element Visibility

`nodisplay(e) nodisplay(id) ND(e) ND(id)`	Instead of: `e.style.display = "none";` Use any of the following: `PF.nodisplay(e); PF.nodisplay('mydiv'); PF.ND(‘mydiv’);`
`T(e, text) T(id, text) setInnerText(e, text)`	Instead of: `if (mz) e.textContent = text; else e.innerText = text;` Use either of the following: `PF.T('mydiv', 'text to set'); PF.T(e, 'text to set');`
`display(id) D(e) D(id)`	Instead of: `e.style.display = "block";` Use any of the following: `PF.display(e); PF.display('mydiv'); PF.D(‘mydiv’);`
`isVisible(e) isVisible(id)`	Returns true if the element is visible; false otherwise.
`clearDisplay(el)`	Clears the e.style.display property and reverts to what is defined in CSS.
`hide(el)`	Sets visibility style to hidden.
`visible(el)`	Sets visibility style to visible.
`toggleDisplay(el)`	Toggles display attribute to show/hide element.
`switch(display, nodisplay)`	Displays the first item and hides the second item. `PF.switch( divToShow, divToHide )`
`toggleVisibility(name)`	Toggle display style between “none” and “block”.
`canYouSeeMe(target)`	Returns `true` if the item is visible on the screen, or `false` if it is not visible. It does so by walking through the ancestors and checking whether any of them has the `display` attribute set to `none` or the `visibility` attribute set to `hidden`.
