Configure the analyse startup method to avoid OOM `OutOfMemoryError`

[michaelphop]

I am analyzing a very large project (cs:2-type).
After few hours of analysis I get OOM: Java heap space.

Attached the stack trace:

Firstly check your startup method based on #14. Then make sure that the memory of your machine is enough to analyze so large project.
