Allow users to set colormap thresholds when loading images about nsviewer

[tyarkoni]

You can now specify 'positiveThreshold' and 'negativeThreshold' properties in Image objects.

Excellent! It works nicely, except for one thing. Is there a way to force the text input linked to the slider, e.g.

viewer.addSlider('pos-threshold', '.slider#pos-threshold', 'horizontal',  0, 1, 0, 0.01, null, '#pos-threshold-text');
<input class="slider-text" id="pos-threshold-text" />
<div class="slider layer_settings" id='pos-threshold'></div>

to update when the image loads?

I think I just fixed this in my last push. Try and see. If it still doesn't work, let me know. As a workaround, you can always do Viewer.selectLayer(0), which should activate the 0th layer and update the view accordingly.

hmm, it doesn't seem to work for me with the new nsviewer pull or with your
workaround (calling viewer.selectLayer(0) right after
viewer.loadImages(images) )

maybe I have the text box declared wrong? if I just nudge the slider, it
displays the right value.

in case it's useful for debugging, i'm serving my app here for the time
being: http://stanford.io/17mMW8t
