2016-02-27: -Merged current developer state of OpenMS.
            -Fix bug in IMSTraceExtractor that lead to not generating Features in maps with many empty spectra.

2015-09-28: -New tool IMSMedianFilter for baseline filtering along Drift or RT.
            -New tool IMSGnuPlotExporter writing a tsv (similar to dta2d) where single spectra are separated by a blank line.
            -GUI: Axis labels can be increased/decreased in 1D/2D/3D (but not projection view) with Ctrl+L and Ctrl+Shift+L.
            -Adapted mobility unit representation to fix wrong symbol issue on windows.
            -In IMSPeakTableCreator the mode for chromatogram generation (used for estimating RT related parameter estimation) can now be controlled via parameters.
            -FIX: Processing history is no longer deleted by IMSMapTranspose.
            -FIX: Crash of IMSPeakTableCreator due to application of Savitzky Golay filter on few points.
            -FIX: Internal changes to increase code stability.
    
2014-06-30: -fixed issue with crashes due to integration in wrong layer (Ticket #7)
            -added option to switch between stick view and triangulation view in 3D (Ticket #23)
            -1D integration results can now be merged into a single layer (Ticket #11)
            -axis scaling is preserved after integration (Ticket #15)
            -for every feature (3D integration result) the bounding box information in displayed on mouseover (Ticket #18)
            -minor bugfixes
            -hotkey for numerical integration
            -IMSExporter now scales intensities to mV. Has a parameter to set the input unit as V or mV (default V)

2014-03-21: -changed drift projection scale: percentage -> absolute
            -changed drift projection to continuous line
            -increased number of bins for drift projection: 100 -> 1000 
            -rt/drift/intensity displayed with 4 significant digits, e.g. 1.1234
2014-03-12: -bugfis in 'Numerical integration'
2014-03-10: -added correct annotation of 3D centroid when integrating
2014-02-24: -added 2D and 3D calculation for the area under the curve (integral)
            -2D integration is done with a baseline correction. the baseline is a straight line between the start- and end=point of the chosen interval. 
            -3D integration is done without a baseline correction
2014-02-19: -added csv support for IMSExporter
            -changed drift axis label to 'drift[msec]'

2014-01-06: -corrected IMSExporter default settings, added TOPPAS workflow

2014-01-04: -added IMSExporter conversion tool to OpenMS
            -The converter is now integrated in OpenMS as TOPP tool and can be used as part of a TOPPAS pipeline.
