function New-JMeterAggregateReport {
    <#
    .SYNOPSIS
    Takes input JMeter JTL file (and optionally PerfMon CSV) and generates aggregate report in html format (JMeter-AggregateReport.html).
 
    .DESCRIPTION
    It runs the following:
    1) Generate AggregateReport in csv format (using JMeterPluginsCMD - generates Aggregate Report in csv format).
    2) Generate other reports (specified in ImagesToGenerate) in png format.
    3) Create html report basing on the output generated in the steps above.
 
    .PARAMETER JMeterDir
    Path to JMeter directory.
 
    .PARAMETER InputJtlFilePath
    Path to the input JTL file.
 
    .PARAMETER OutputDir
    Output directory where .html / .png / .csv files will be generated.
 
    .PARAMETER InputPerfMonFilePath
    Path to the input PerfMon file (optional).
 
    .PARAMETER JavaPath
    Optional path to java.exe that will be used by JMeter CMDRunner.
     
    .PARAMETER WarningThresholds
    String containing warning thresholds for each column. For example if $WarningThresholds = 'Average=3000,Max=30000,Error %=0',
    samples with Average > 3000, Max > 30000 or Error % > 0 will be marked red in the output html.
 
    .PARAMETER TimeoutInSeconds
    Timeout to wait for external process (CMDRunner) to be finished.
 
    .PARAMETER CustomCMDRunnerCommandLines
    List of custom command line parameters - each will be passed to a separate invocation of CMDRunner.
 
    .EXAMPLE
    New-JMeterAggregateReport -JMeterDir "c:\workspace\TeamCityLibraries\JMeterIntegration\lib\apache-jmeter-2.11" `
        -InputJtlFilePath "C:\workspace\TeamCityLibraries\JMeterIntegration\test\visualizer.jtl" `
        -InputPerfMonFilePath "C:\workspace\TeamCityLibraries\JMeterIntegration\test\perfmon.csv" `
        -OutputDir "C:\workspace\TeamCityLibraries\JMeterIntegration\ReportOutput"
