    <#
    .SYNOPSIS
        Sets current minimum level of logger configuration
    .DESCRIPTION
        Sets current minimum level of logger configuration, below which no events should be generated.
    .PARAMETER LoggerConfig
        Instance of LoggerConfiguration
    .PARAMETER Value
        The current minimum level, below which no events should be generated.
    .PARAMETER ToPreference
        Set to propagate desired minimum level to preference variables.
    .PARAMETER ControlledBy
        Sets the minimum level to be dynamically controlled by the provided switch
    .PARAMETER FromPreference
        Sets the minimum level according to the lowest preference variable. For example if $DebugPreference -eq 'Continue' and $VerbosePreference -eq 'SilentlyContinue' then minimum level will be Debug.
    .INPUTS
        Instance of LoggerConfiguration
    .OUTPUTS
        Instance of LoggerConfiguration object allowing method chaining with altered minumum logging level
