Get Processor Temperature from Powershell

## This will get the processor temperature from WMI and optionally log to a file with DTG


## Usage:
##
## Get-Temperature [-logfile %LOGFILELOCATION%]
## -logfile is optional - if it is left out, the output will be displayed on the screen
##
## eg:
## Get-Temperature
## Get-Temperature -logfile "h:\TempLog.csv"

# You **must** run as Administrator.
