.EXAMPLE
    Set-R53Record -Domain mypowershell.space -Type A -Name www -Value 1.2.3.4 -TTL 300
    Create an A record to point www.mypowershell.space to IP 1.2.3.4. TTL set to 5 minutes.
.EXAMPLE
    Set-R53Record -Domain mypowershell.space -Type A -Name mail -Value 1.2.3.4 -TTL 3600 -Comment "mail entry"
    Create an A record to point mail.mypowershell.space to IP 1.2.3.4. TTL set to 60 minutes and has an optional comment.
.EXAMPLE
    Set-R53Record -Domain mypowershell.space -Type TXT -Name _amazonses -Value "G3LNeKkT8eYmQLeyAp" -Comment "confirm domain ownership"
    Create a TXT record to set _amazonses.mypowershell.space to "G3LNeKkT8eYmQLeyAp" and confirm domain ownership. Will use default TTL (300) and no comment.
.PARAMETER Domain
    Defines a domain which DNS zone is to be edited:
    1. mypowershell.space
    2. amazon.com
    3. google.com.
    4. facebook.com.
.PARAMETER Type
    Defines a type of a DNS record: A, TXT, MX, CNAME, NS...
    Most likely won't support all. If you mod the script and add functionality, let me know!
.PARAMETER Name
    Defines a name of a DNS record: www, mail, intranet, dev...
.PARAMETER Value
    Defines a value of DNS record:
    1. 192.168.0.1
    2. "ZTJGIJ4OIJS9J3560S"
    Bear in mind which record type is numerical and which textual!
.PARAMETER TTL
    Defines a TTL of DNS record. I shouldn't really need to explain this :-)
    Not mandatory, defaults to 300.
.PARAMETER Comment
    Defines an optional R53 comment.
    Not mandatory, not included if not explicitly defined.

    Changes an EC2 instance type leaving it in the same state

   Shutting down Instance i-1234567890abcdef
   ........
 
   InstanceID Status InstanceType
   ---------- ------ ------------
   i-1234567890abcdef running m4.large
 
   In this example one instance was specified for changing running and was stopped, changed and started again.
    
.EXAMPLE
   C:\> (Get-EC2instances).instances | Where {$_.InstanceType -eq "t2.large"} | Set-CMEC2InstanceType -InstanceType m4.large
 
   Shutting down Instance i-1234567890fedcba
   ........
 
   InstanceID Status InstanceType
   ---------- ------ ------------
   i-1234567890fedcba running m4.large
   i-1234567890abcdef stopped m4.large
 
   In this example all the instances that were of instance type t2.large where changed to m4.large, of which there were two. However, one of the instances was in a stopped state and the other was running and they were both left in their respective states.
