Can't convert Slice layer & Eltwise layer from caffe to mxnet?

The following is output:

Traceback (most recent call last):
File "convert_symbol.py", line 164, in
main()
File "convert_symbol.py", line 156, in main
symbol_string, output_name = proto2script(sys.argv[1])
File "convert_symbol.py", line 122, in proto2script
raise Exception('Unknown Layer %s!' % layer[i].type)
Exception: Unknown Layer Slice!

This was because these layer may not yet be supported in mxnet, or the mapping was not yet added. Please feel free to open a issue on each operators(layer) that is missing, and we can find ways to add them, or give guidance on how they can be added

This is part of the #404 (no pun intended) issue.
