Debugging.

[romansl]

For practical use library needs strong debug functionality. If something goes wrong it is hard to understand the reason. Other libs has interesting tools for it.

For example: https://github.com/jaredly/rxvision

Tools we need:

1. Memory leak detector.
2. Tree structure viewer.
3. Runtime operations printer.

For my implementation I workong on Tree Viewer. Single function dump(s: Stream<*>) prints to log tree structure in dot format.

For example this structure of function Stream.collect from testCollect:

digraph G {
{node [shape=box;style=filled;color=lightgrey;]"Node:19651F3";"Node:157696F";"Node:67C67E";"Node:BC8AB5";"Node:C1670B";"Node:1B21B69";"Node:7080DC";}
"Node:19651F3" [label="map - StreamImpl.kt:192\nrank=2"];
"Node:157696F" [label="snapshot - StreamImpl.kt:188\nrank=1"];
"Node:67C67E" [label="Node:67C67E\nrank=9223372036854775807"];
"Node:BC8AB5" [label="<init> - StreamImpl.kt:186\nrank=3"];
"Node:C1670B" [label="<init> - Sodium.kt:14\nrank=0"];
"Node:1B21B69" [label="map - StreamImpl.kt:189\nrank=2"];
"Node:7080DC" [label="lastFiringOnly - CellImpl.kt:23\nrank=4"];
"Node:C1670B" -> "Target:18D30F7"
"Target:18D30F7" -> "Node:157696F"
"Target:18D30F7" -> "action:1D2A7E8"
"Node:157696F" -> "Target:57CD70"
"Target:57CD70" -> "Node:1B21B69"
"Target:57CD70" -> "action:9273A8"
"Node:1B21B69" -> "Target:7D1D39"
"Target:7D1D39" -> "Node:67C67E"
"Target:7D1D39" -> "action:A7B76D"
"Node:157696F" -> "Target:1A7504C"
"Target:1A7504C" -> "Node:19651F3"
"Target:1A7504C" -> "action:BDB505"
"Node:19651F3" -> "Target:39AC6"
"Target:39AC6" -> "Node:BC8AB5"
"Target:39AC6" -> "action:E6A65D"
"Node:BC8AB5" -> "Target:16E852B"
"Target:16E852B" -> "Node:7080DC"
"Target:16E852B" -> "action:100955A"
"Node:7080DC" -> "Target:D2FA64"
"Target:D2FA64" -> "Node:67C67E"
"Target:D2FA64" -> "action:874448"
}

Yes - these are great things to do. I don't have time for any of it at the moment but let's leave this open.
