fixed wrong link in example
added start and stop functions, events, ++

-added events on convergence, iteration, loss of tracking, and if no
face found
-added function start and stop, for continuous tracking
-reorganized code
-changed name of getMovementSum to getConvergence
small fixes to last commit
updated examples

fixed examples to use new clmtrackr functions
updated model and response calculations

-Added a new model, with optimized C in SVM fitting
-fixed normalization in webgl code, so that it matches fitting code.
Chose normalization to 0-1, since normalization by unit variance gave
poorer results
added gradient filter model

-added sobel gradient filter (model_pca_20_sobel.js) and webgl
calculations for sobel gradient (svmfilter_webgl_sobel.js)
-some cleanup in svmfilter_webgl.js
-optimized svr filter some more
added logistic response function

-added logistic response functions to mossefilter and fft svmfilter
added example and compiled version

-added usage example
-added compiled versions of clmtrackr
Fixed bugs in tracking, added options

-added possibility to weight points of pdm model (in order to increase
fit for those points)
-option to increase sharpness of response (by self-multiplication)
-fixed logistic transformation on fft response calculation
-removed option of having filters that are not odd dimensions in webgl
filter (to simplify code)
-fixed numerous bugs regarding correct size of search window in clm.js,
svmfilter_webgl.js, svmfilter_fft.js, svmfilter_webgl_sobel.js
-recompiled clmtrackr.js
Updated models with new PDM

-updated models, new pdm
-updated examples
modified getConvergence

Modified way of calculating convergence, to avoid issues with
nonconvergence when optimization oscillates around target
Fixed bug in meanshift calculation

-meanshift calculations need to be scaled to the tracked face
-modified variance sequence to increase tracking quality after bug was
fixed
Cleanup

removed old unmaintained branches of clm.js
Fixed bug in rotation

Fixed bug in calculation of rotation and scaling
Fixed presets in face deformation example
Updated model images in readme.md
Rebuilt clmtrackr.js ++

-Rebuilt clmtrackr.js & min.js
-fixed wrong dimensions of video in example.html
