Test for unimodality

[guadapascal]

Hello!

I want to understand your own test for unimodality (based on Hartigan and Hartigan, 1985) but I can't found it in the code.
Perhaps, I am looking for this in a incorrect code or I can't understand a sentences in C++.
Would you help me please? Where can i found the test? I guess If i see the algorithm before C++ sentences, it would be perfect for understand the test.

Thank you!
