Add linux, and preliminary mac, support

[AljenU]

Update the code with switches, where necessary, to support windows and mac and linux.

Mainly in setup and buildinterface, and some cpp header files, different paths need to be followed for different operating systems.

Closes #17 Nearly all of #18, except for one last step that is blocking correct execution on mac.

@edovanveen Please do check that this branch works correctly, including build_interface, on Windows.

I reran build_interface, and runtests +tests runs without failed tests.

I do get some new warnings during the build process that I did not get before, but those can be safely ignored:

>> utils.build_interface

C++ compiler set to 'MinGW64 Compiler (C++)'.
Definition file defineneuron.m contains definitions for 183 constructs supported by MATLAB.
- 167 construct(s) are fully defined.
- 16 construct(s) partially defined and commented out.

To include the 16 undefined construct(s) in the interface, uncomment and complete the definitions in defineneuron.m.
To build the interface, call build(defineneuron).

@ramcdougal : This branch should now be ok to try out on Linux.

The following tests results differ numerically on Linux from the results on Windows, sometimes quite a bit. Does that also happen for you?

I see the same test failures on my Linux machine...
