This implementation takes two user inputs with ''Get-AngleDiff'' or prints the
examples with ''Get-Examples''. There is also a full help file accessed by typing
''Get-Help Get-AngleDiff -full''

.Synopsis
Gets the difference between two angles between the values of -180 and 180.
To see examples use "Get-Examples"
.DESCRIPTION
This code uses the modulo operator, this is represented with the "%".
The modulo operator returns the remainder after division, as displayed below
3 % 2 = 1
20 % 15 = 5
200 % 146 = 54
.EXAMPLE
PS C:\WINDOWS\system32> Get-AngleDiff
cmdlet Get-AngleDiff at command pipeline position 1
Supply values for the following parameters:
angle1: 45
angle2: -85
The difference between 45 and -85 is -130
PS C:\WINDOWS\system32>
.EXAMPLE
PS C:\WINDOWS\system32> Get-AngleDiff -angle1 50 -angle2 -65
The difference between 50 and -65 is -115
PS C:\WINDOWS\system32>
.EXAMPLE
PS C:\WINDOWS\system32> Get-AngleDiff -89 50
The difference between -89 and 50 is 139
PS C:\WINDOWS\system32>
