function Get-TabXaml {
    <#
    .SYNOPSIS
        Generates XAML for a tab in the WinUtil GUI
        This function is used to generate the XAML for the applications tab in the WinUtil GUI
        It takes the tabname and the number of columns to display the applications in as input and returns the XAML for the tab as output
    .PARAMETER tabname
        The name of the tab to generate XAML for
        Note: the 'tabname' parameter must equal one of the json files found in $sync.configs variable
              Otherwise, it'll throw an exception
    .PARAMETER columncount
        The number of columns to display the applications in, default is 0
    .OUTPUTS
        The XAML for the tab
    .EXAMPLE
        Get-TabXaml "applications" 3
