Required: Visual Studio 2015 or 2017 (or probably later works)

Setup
1. Clone/download OpenSSL 1.1.1 source to a folder
2. Download / install Perl (They recommend Active perl)
   I recommend using Chocolatey so for me: choco install activeperl
3. Ensure Perl is in the system path. (Choco appears to do this by default)
4. Download / install NASM
   I recommend using Chocolatey so for me: choco install nasm
5. Ensure NASM is in the system path. (For me the directory to add was C:\Program Files\NASM)

# Using QThreads in PyQt5 using worker model

# There is so many conflicting posts on how QThreads should be used in pyqt. I had
# been subclassing QThread, overriding the run function, and calling start to run
# the thread. I did it this way, because I couldn't get the worker method (where 
# an object is moved to a thread using moveToThread) to do what I wanted. It turns
# out that I just didn't understand why. But, once I worked it out I have stuck with
# the moveToThread method, as this is recommended by the official docs. 
# 
# The key part for me to understand was that when I am running a heavy calculation in

# by separate threads, and passed back to the gui thread for plotting.
# This is an example of using movetothread, which is the correct way of using QThreads
