1) Check that ws, stride and pad are int
2) Check that padding is zero when ignore border is false (not
supported)
3) Check that window shape is less than pad (not supported)

Correct way is to first compute window end and only after that clip
window start.

add doc version switcher to top of sidebar

Make corrMM work in float16/64

Added checks for taps values.

Fix remaining tests in debugmode

Update to fix python 3 error

Option to evaluate part of the max-and-argmax on cpu

Numpy imports

Fix h_softmax example data types

Fix grad of elemwise with boolean inputs.

Commented code removed, and assertion added to check that call to sys.getrefcount does nots changes the refcount.

Update test function test_pycuda_memory_to_theano() to fix Python 3 error.

The refcount of a variable seems to be different between Python 2 and Python 3. So it seems better to stock an initial refcount in a variable and then do the checkings with that variable instead of directly using comparing to constant values.

Tests passed with Python 3 (Anaconda):

```
$ nosetests --verbose --nocapture theano/misc/tests/test_pycuda_theano_simple.py
Run pycuda only example to test that pycuda works. ... ok
Simple example with pycuda function and Theano CudaNdarray object. ... ok
theano.misc.tests.test_pycuda_theano_simple.test_pycuda_memory_to_theano ... 4
gpuarray ref count before creating a CudaNdarray 4
strides (20, 5, 1)
gpuarray ref count after creating a CudaNdarray 5
gpuarray ref count after deleting the CudaNdarray 4
