Tests if a value is a Windows absolute path.

@param {*} value - value to test
@returns {boolean} boolean indicating if a value is a Windows absolute path

@example
var bool = isAbsolutePath( 'C:\\foo\\bar\\baz' );
// returns true

@example
var bool = isAbsolutePath( 'foo\\bar\\baz' );
// returns false
