* Making Matlab work out-of the box with COMSOL

* comsol: `prepend_path` for MATLABPATH

Bug relates to the interplay between:
1. random dict orders in python 3.5
2. bugfix in initial implementation of stacks for `_concretize_dependencies`
   when `self._dependencies` is empty
3. bug in coconcretization algorithm computation of split specs

Result was transient hang in coconcretization.
Fixed #3 (bug in coconcretization) to resolve.

Whenever attempting to use any ncurses functionality within cscope, a
page fault would result within the ncurses library.

    Program received signal SIGSEGV, Segmentation fault.
    0x00007ffff7fad3cf in termattrs_sp () from .../lib/libncursesw.so.6
    (gdb) bt

This is due to a conflict between libtinfo.so and libtinfow.so. Both are
linked into cscope:

    $ ldd $(which cscope)
    /bin/bash: .../lib/libtinfo.so.6: no version information available (required by /bin/bash)
        linux-vdso.so.1 (0x00007fff5dbcb000)
        libncursesw.so.6 => .../lib/libncursesw.so.6 (0x00007f435cc69000)
        libtinfo.so.6 => .../lib/libtinfo.so.6 (0x00007f435cc2c000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f435ca29000)
        libtinfow.so.6 => .../lib/libtinfow.so.6 (0x00007f435c9e8000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f435cca7000)

Specifically linking libtinfow.so instead of libtinfo.so resolves the
issue.
