Function New-AGMLibGCPInstanceMultiMount ([string]$instancelist,[switch]$textoutput,[decimal]$limit) 
{
    <#
    .SYNOPSIS
    Uses a pre-prepared CSV list of GCP Instance data to create many new GCP Instances

    .EXAMPLE
    New-AGMLibGCPInstanceMultiMount -instancelist recoverylist.csv

    This will load the contents of the file recoverylist.csv and use it to run multiple New-AGMLibGCPInstance jobs

    .EXAMPLE
    New-AGMLibGCPInstanceMultiMount -instancelist recoverylist.csv -textoutput

    This will load the contents of the file recoverylist.csv and use it to run multiple New-AGMLibGCPInstance jobs
    Rather than wait for all jobs to be attemped before reporting status, a report will be displayed after each job is attempted.

    .DESCRIPTION
    This routine needs a well formatted CSV file. Here is an example of such a file:

    srcid,appname,projectname,zone,instancename,machinetype,serviceaccount,networktags,poweronvm,labels,disktype,nic0hostproject,nic0network,nic0subnet,nic0externalip,nic0internalip,nic1hostproject,nic1network,nic1subnet,nic1externalip,nic1internalip
    28417,lab2tiny,project1,australia-southeast1-a,gcetest2,e2-micro,,,TRUE,,pd-ssd,,network3,sydney,,,,,,
    28417,mysq57,project1,australia-southeast1-a,gcetest3,e2-micro,,,TRUE,,pd-ssd,,network3,sydney,,,,,,
    28417,postgres11,project1,australia-southeast1-a,gcetest4,e2-micro,,,TRUE,,pd-ssd,,network3,sydney,,,,,,
 
    If you specify both appname and appid then appid will be used. The appname is mandatory so you know the name of the source VM.
