.SYNOPSIS
    Creates a custom error record.
.DESCRIPTION
    This cmdlet generates a custom error record. Custom error 
    records can be used to provide additional or tailored 
    information to the user when encountering an exception.
.PARAMETER Message
    The text error message to display to the user. This should
    be desciptive of the error encountered.
.PARAMETER Exception
    The name of an exception. Valid exception names are:
        AccessViolationException
        AggregateException
        AppDomainUnloadedException
        ApplicationException
        ArgumentException
        ArgumentNullException
        ArgumentOutOfRangeException
        ArithmeticException
        ArrayTypeMismatchException
        BadImageFormatException
        CannotUnloadAppDomainException
        ContextMarshalException
        DataMisalignedException
        DivideByZeroException
        DllNotFoundException
        DuplicateWaitObjectException
        EntryPointNotFoundException
        Exception
        ExecutionEngineException
        FieldAccessException
        FormatException
        IndexOutOfRangeException
        InsufficientExecutionStackException
        InsufficientMemoryException
        InvalidCastException
        InvalidOperationException
        InvalidProgramException
        InvalidTimeZoneException
        MemberAccessException
        MethodAccessException
        MissingFieldException
        MissingMemberException
        MissingMethodException
        MulticastNotSupportedException
        NotFiniteNumberException
        NotImplementedException
        NotSupportedException
        NullReferenceException
        OperationCanceledException
        OutOfMemoryException
        OverflowException
        PlatformNotSupportedException
        RankException
        StackOverflowException
        SystemException
        TimeoutException
        TimeZoneNotFoundException
        TypeAccessException
        TypeLoadException
        TypeUnloadedException
        UnauthorizedAccessException
        UriFormatException
        UriTemplateMatchException
.PARAMETER ErrorID
    A string identifying the error. This is freeform, but should not be 
    the same as an alredy defined error ID. In native PowerShell errors,
    this parameter sets the 'FullyQualifiedErrorID' field.
.PARAMETER ErrorCategory
    An error category from [System.Management.Automation.ErrorCategory]
    that categorizes the error being thrown.
.PARAMETER TargetObject
    The object that was being processed when the error was encountered.
.PARAMETER InnerException
    The exception that caused the exception triggering the creation of
    this error record.
.EXAMPLE
    New-ErrorRecord -Exception InvalidOperationException -Message 'The value provided in CollectionName is invalid.' -ErrorCategory InvalidArgument -ErrorID 'InvalidCollectionIdentifier'

    The value provided in CollectionName is invalid.
        + CategoryInfo          : InvalidArgument: (:) [], InvalidOperationException
        + FullyQualifiedErrorId : InvalidCollectionIdentifier

    The command above creates an InvalidOperationException error record and outputs a meaningful 
    message to the screen.
.EXAMPLE
    New-ErrorRecord 'This is the error message' UnauthorizedAccessException 'ErrorID' PermissionDenied
    
    This is the error message
        + CategoryInfo          : PermissionDenied: (:) [], UnauthorizedAccessException
        + FullyQualifiedErrorId : ErrorID
    
    The above command generates an UnauthorizedAccessException error record using positional arguments.
.EXAMPLE
    try
    {
        17 / 0
    }
    catch
    {
        New-ErrorRecord -Message 'Attempted to divide by zero.' -Exception DivideByZeroException -ErrorID 'DivideByZero' -ErrorCategory InvalidArgument -InnerException $PSItem.InnerException
    }
    Attempted to divide by zero.
        + CategoryInfo          : InvalidArgument: (:) [], DivideByZeroException
        + FullyQualifiedErrorId : DivideByZero

    This contrived example makes use of the InnerException parameter.
