New features for editing/proofreading traced neurons

[gnayuy]

Requested by Yun Wang.

1. manually set a radius adjustable landmark to separate 1 neuron tree into 2 neuron trees, the color of each separated neuron tree can be assigned at this time;

2. after completing one part of neuron tracing, the color can be assigned at this time;

3. be able to connect the multiple selected traced segments into a single neuron tree; current issue of the automated method is going to create some unnecessary incorrect connections;

4. be able to autotrace neurons in a small local window;

5. support clicking a "incomplete end (ie) point" from the "ie" list and the 3D window will go to the field of view of 1:1 resolution corresponding block; current function will go back to a coarser resolution block;

6. (nice to have) global lower resolution whole mouse brain rendering / navigation map.

7. Individual dendrites and an axon of a neuron are connected as independent trees.

This would be amazing. Have any of these features been updated?
