/*
This js function will find the index of an array element with the given value in an array.
for Example you are having an array like

var mnuArray = new Array("Groups","Services","Applications");

And want to know the index/position of and element in an array, then
you can call mnuArray.findIndex("Services");
This will return "1".

This will be helpful if you are having a large size array/the elements are unknown which you have populated from an dB

If you want to do the same in the case of multidimensional arrays
then use the following
