[cliviu74]

Fix for #49

• add timeout to post/put requests
• minor code formatting

[tmenguy]

great, the only issue I has with this is the variable name : it is called GetTimeout .... and we use it everywhere, I preferred th let it as it is to no break any compatibility. Anyway great to have the fix, hope you can merge it soon so we can merge the #46 right after

Agreed with the *getTimeout, should be more general.
I'll think about a refactor, pending finding some time.
