test_suite: add docs so matlab makefile doesn't error on this
Matlab conversion: try to ignore "error" and "xfail" tests

The probably better option would be to try to create matlab tests
using their test framework.
Merge remote-tracking branch 'origin/master' into depr2
remove some octave-specific commands
matlab fixes, removing octave-specific syntax
Merge remote-tracking branch 'origin/master' into depr2

Conflicts:
	inst/@sym/logical.m
fix for matlab syntax
matlab syntax fixes
Matlab disable warnings: doesn't support 'local' arg

Use something that works in both Octave and Matlab
fix octave-specific code

must try to remember that assert() only takes a logical on Matlab
Matlab: workaround for issue #107
octsympy on matlab: disable some ezplot tests

should fix up later!
matlab fixes, and fix tests for isfinite
matlab: run tests in random order (temporarily?)

make debugging a bit easier while I have a lot of them to fix.
matlab: the strings in msgid's, between : must be valid names
matlab: for now, skip expected warnings
symfun: numel=1, size=(1,1), helps with matlab and also matches SMT

SMT does this.  This nicely works around lots of instances of #107 too.
Perhaps leave open for now.

Fixes #109.
