        .PARAMETER NoVersionCheck
            Prevents MCCA from determining if it's running the latest version. It's always very important to be running the latest
            version of MCCA. We will change guidelines as the product and the recommended practices article changes. Not running the
            latest version might provide recommendations that are no longer valid.
 
        .PARAMETER Geo
            This will generate a report based on the geolocations entered by you.You need to input appropriate numbers from the following list corresponding to the regions.
            Input Region
                1 Asia-Pacific
                2 Australia
                3 Canada
                4 Europe (excl. France) / Middle East / Africa

        .PARAMETER Solution
            This will generate a report only for the solutions entered by you. You need to input appropriate numbers from the following list corresponding to the solution.
            Input Solution
                1 Data Loss Prevention
                2 Information Protection
                3 Information Governance
                4 Records Management
                5 Communication Compliance
                6 Insider Risk Management
                7 Audit
                8 eDiscovery
 
        .PARAMETER Collection
            Internal only.
        .EXAMPLE
            Get-MCCAReport
            This will generate a customized report based on the geolocation of your tenant. If an error occurs while fetching your tenant's geolocation, you will get a report covering all supported geolocations.
        .EXAMPLE
            Get-MCCAReport -Geo @(1,7)
            This will generate a customized report based on the geolocations entered by you.
        .EXAMPLE
            Get-MCCAReport -Solution @(1,7)
            This will generate a customized report for the solutions entered by you.
        .EXAMPLE
            Get-MCCAReport -Solution @(1,7) -Geo @(9)
            This will generate a report only on for the solutions entered by you and based on the regions you have selected.
