Size at start of effort

Concern raised about the size of core lib&utils directory. Most of the code is in:

1. UniformStore and related classes,
2. formatCompilerLog
3. loadFile etc

lib

$ ls -Rl lib/**/*.js

dependencies

These are probably big drivers

• probe.gl/log
• probe.gl/stats
• math.gl?

adapter/type-utiles etc

There is also type utilities these are not yet measured...
