BrowserDetect

The BrowserDetect object is initiated on window load,
any javascript run after window load will have access
to the following information:

	BrowserDetect.isIE
		- returns boolean true or false
	
	BrowserDetect.getVer()
		- returns full version (i.e. 5.5, 6.0, 7.0, 7.0b, etc.)
	
	BrowserDetect.getMajorVer()
		- returns only the major version (i.e. 5, 6, 7, 7, etc.)
	
	BrowserDetect.getMinorVer()
		- returns only the minor version (i.e. 5, 0, 0, 0b, etc.)

~all tested in IE5.5 - IE7.0~

NOTE:  Currently only provides version information
for IE. Support for Firefox and Safari may be added
at a later stage.
