SoftwareLockin

Made slight changes to make the lockin code from https://leso.epfl.ch/cms/site/leso/lang/fr/pcsc-lockin http://leso2.epfl.ch/downloads/PCSC-Lockin/lockin.tar.gz

Code is originally written for QT4. To build it on QT5, the following changes were made:

1. edited the pro files to add the line QT += widgets

2. edited vumeter.h etc changing QtGui/QWidget to QWidget

3. changed all references of toAscii() to toLatin1() in lockin.cpp and dockoutput.cpp

as per http://doc.qt.io/qt-5/qstring-obsolete.html

Also, in order to build, on a fresh install of Ubuntu or Mint, you will need to do

sudo apt-get update

sudo apt-get install build-essential

and then proceed to install the other required dev libraries as per the INSTALL file.
