Library usage questions

[andrey-gvrd]

I understand that this library still under development, but I had a couple of question regarding the use of it.

For example -- in a GET request in examples/timeapi-test.cpp:
Where is the server's request returned to?
Why do I have to declare these global variables in my code:

const int g_port = 443;
bool g_https_complete;
uint32 g_bytes_received;

When should I call httpsclientSetup?
What does httpsclientCleanUp do and why isn't it called after a successful transaction?
If dynamic memory allocation is not used, what's the purpose of the System.freeMemory(); call?
