    ECHO This script builds all of the components ^(Web UI, .Net microservices, and the API gateway^) that are
    ECHO used by IoT Device Simulation deployments. It builds Docker containers for each and pushes them
    ECHO to the Docker container repository for the currently logged in user. A deployed IoT Device Simulation
    ECHO solution includes an Azure VM image that references these containers at startup.
    ECHO.
    ECHO Usage:
    ECHO  --prefix:  the Docker repository to push to
    ECHO  --service: [optional] a specific microservices or component to build. Available options include:
    ECHO             %ALLCOMPONENTS%
    ECHO  --tag:     [optional] the Docker tag to use for each Docker image build. The default value is 'latest'
    ECHO.
    ECHO Examples:
    ECHO  .\buildAndPush --prefix examplereponame
    ECHO  .\buildAndPush --prefix examplereponame --service device-simulation-dotnet
