Uses windows directory separator in examples

[RonaldDuncan]

e.g. In examples
xbrlDoc1.Load(@"............\JeffFerguson.Gepsio.Test\XBRL-CONF-2014-12-10\Common\300-instance\301-01-IdScopeValid.xml");
I think the Linux/Mac directory separator works for both Windows and Linux,but not yet tested on Windows works on Linux.
xbrlDoc1.Load(@"../../../../../../JeffFerguson.Gepsio.Test/XBRL-CONF-2014-12-10/Common/300-instance/301-01-IdScopeValid.xml");
