/*
Usage:

- Place a link to the script file in the <head> region of any page on which you 
wish to use the script:

<script type="text/javascript" src="p7_eqCols2_10.js"></script>

Make sure you adjust the path to reflect the actual location of the script file 
relative to your document.

- Place an onLoad call on your page's <body> tag:

<body onLoad="P7_equalCols2(1,'c1','P','c2','P')">

The onLoad call contains the animation option (1=yes, 0=no) and then lists the 
target DIVs and the tags we wish to use in parentheses, separated by commas: 
'c1','P','c2','P'. These are called the arguments. They are the IDs of the DIVs 
you want to set to equal height. In this example, you want a DIV with an ID of 
c1 and another DIV with an ID of c2 to be set to equal height, using paragraph 
'P' tags as the object to meaure against.
