<#
    .SYNOPSIS
    Converts a CSV file to message objects for posting to salesforce APIs
 
    .DESCRIPTION
    The CSV file must contain the following columns:
 
        "Type" - either "Measurement" or "Survey"
        "MinuteOffset" - the offset in minutes from StartDate
        "Name" - Either the name of the measurement type or the name of the survey
 
        The additional columns required are determined by the value of each row in the Type and Name columns
 
        For Type="Survey":
 
            The "AnswerFile" column is required. It must specify the name of the file that contains the survey responses.
            See help on Get-SurveyResponsesFromCsv for a description of the format of this file.
 
            Example:
            "MinuteOffset","Type","Name","AnswerFile"
            "0","Survey","Blood Pressure Change Survey"
 
        For Type="Measurement":
 
            The Measurment name must match a measurement name eCC phecc__Measurement_Type__c table in the org
            A column can be added for each Metric name from the 'phecc__Metric__c' table in the org
            If the column is present the value in this column is used for the message
            And additional column is required to specify the units for the metric. The column must be named '<metric name>:units"
            The value must must be a valid unit for the metric from the 'phecc__Unit__c' table in the org
 
            Example:
            "MinuteOffset","Type","Name","Pulse (Average) - Wearable","Pulse (Average) - Wearable:units"
            "0","Measurement","Wearable","71","Bpm"
 
    .INPUTS
    None. You cannot pipe objects to Get-CdrPatients.
 
    .OUTPUTS
    None.
 
    .PARAMETER CsvFile
    The CSV file to read sample data. Defaults to "data.csv"
 
    .PARAMETER Patient
    The patient object
 
    .PARAMETER StartDate
    The StartDate to start inserting the messages using the minute offset of each message
 
    .PARAMETER DeviceType
    The device type to include in all the messages
 
    .PARAMETER DeviceId
    The device id to include in all the messages. Defaults to "1217427502"
 
    .PARAMETER Gateway
    The Gateway to include in all the messages. Defaults to "BioHub"
 
    .PARAMETER GatewayDeviceId
    The Gateway device id to include in all the messages. Defaults to "BioHub:1217427502"
