Steve Lee c1c5344a88 Update copyright and license headers (#6134)
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.

Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.

Separate PR coming to update contribution document for new source files: #6140

Manually reviewed each change.

Fix #6073

# Demo simple interoperation between PowerShell and Python
# Basic execution of a Python script fragment
python -c "print('Hi!')"
# Capture output in a variable
$data = python -c "print('Hi!')"
# And show the data
$data
# Use in expressions
5 + (python -c "print(2 + 3)") + 7
# Create a Python script using a PowerShell here-string, no extension
@"
#!/usr/bin/python3
print('Hi!')
"@ | out-file -encoding ascii hi
# Make it executable
chmod +x hi
# Run it - shows that PowerShell really is a shell
./hi
# A more complex script that outputs JSON
cat class1.py
# Run the script
./class1.py
# Capture the data as structured objects (arrays and hashtables)
$data = ./class1.py | ConvertFrom-JSON
# look at the first element of the returned array
$data[0]
# Look at the second
$data[1]
# Get a specific element from the data
$data[1].buz[1]
# Finally wrap it all up so it looks like a simple PowerShell command
cat class1.ps1
# And run it, treating the output as structured data.
(./class1)[1].buz[1]
# Finally a PowerShell script with in-line Python
cat inline_python.ps1
# and run it
./inline_python
