## New-Script function
## Creates a new script from the most recent commands in history
##################################################################################################
## Example Usage:
##    New-Script ScriptName 4
##        creates a script from the most recent four commands 
##    New-Script ScriptName -id 10,11,12,14
##        creates a script from the specified commands in history
##    New-Script Clipboard 2
##        sends the most recent two commands to the clipboard
##################################################################################################
## As a tip, I use a prompt function something like this to get the ID into the prompt:
##
## function prompt {
##   return "`[{0}]: " -f ((get-history -count 1).Id + 1)
## }
