Warn when the parameter is used, i.e. is not set to None

* Remove decay parameter:
  This parameter is no longer included in the original adam paper

* Fix error in nesterov momentum step:
  The momentum step was additionally multiplied by the learning rate,
  leading to basically zero momentum after a few iterations

* orthogonal initialization

* tests and interface changes
* allow ortho-initialization of tensors
* change leading_dim to shape param
* add unit tests

- arbitrary slices possible
- interface of n_cycles was buggy (0 gave infinite loop, 2 gave 2 cyles)
- add possibility to truncate batch creation if the last batch would
have smaller size (can be solved better, though)
- general cleanup

Merge branch 'iter_minibatches-iterator' of https://github.com/bachard/climin into bachard-iter_minibatches-iterator

* Update signal handler fix for newer numpy/Anaconda version

* Explain changes in comments

produces an iterator without calling minibatches function, thus not creating an array containing all the dataset

added IsNaN stopping criterion

adjusted TimeElapsed for interruptions

added isnan to climin.mathadapt to this end; moreover, some
documentation was added.

added OnSignalWindows/Unix

drop-ins for OnSignal depending on platform
