RStoolbox 0.1.4
=====================================
New:
* new function `validateMap()` for assessing map accuracy separately from model fitting, e.g. after majority or MMU filtering
* new function `getValidation()` to extract specific validation results of superClass objects (proposed by James Duffy)
* new spectral index NDVIc (proposed by Jeff Evans)
* new argument scaleFactor for `spectralIndices()` for calculation of EVI/EVI2 based on scaled reflectance values. 
* implemented dark object subtraction radCor(..,method='sdos') for Landsat 8 data (@BayAludra, #4)

Changes:
* superClass based on polygons now considers only pixels which have their center coordinate within a polygon  
* rasterCVA now returns angles from 0 to 360° instead of 0:45 by quadrant (reported by Martin Wegmann)
* improved dark object DN estimation based on maximum slope of the histogram in `estimateHaze` (@BayAludra, #4)

Fixes:
* superClass failed when neither valData or trainPartition was specified. regression introduced in 0.1.3 (reported by Anna Stephani)
* spectralIndices valid value range of EVI/EVI2 now [-1,1]
* radCor returned smallest integer instead of NA for some NA pixels
* fix 'sdos' for non-contiguous bands in radCor (@BayAludra, #4)


RStoolbox 0.1.3
=====================================
New:
* new logical argument `predict` for superClass. Disables prediction of full raster (validation is still conducted).
* new generic predict() function for superClass objects. Useful to separate model training and prediction. 
* new example data set (landcover training polygons) for lsat example data under /extdata/trainingPolygons.rds 

Fixes:
* fix histMatch for single layers (affected also 'ihs' pan-sharpening)
* fix superClass validation sampling for factors (character based factors could lead to wrong factor conversions and wrong validation results)
* improved handling of of training polygons with overlaps and shared borders in superClass
* improved checks and error messages for insufficient training polygons

RStoolbox 0.1.2
=====================================
New:
New model for superClass: maximum likelihood classification (model = "mlc")

Fixes:
* Restrict calculation of EVI/EVI2 to reflectance data (#3)
* Enforce valid value ranges in radCor: radiance: [0,+Inf], reflectance: [0,1]. Includes a new argument `clamp` to turn this on or off (on by default).
