canonicalise with numeric indices

2

``` {a,b,c}::Indices; {a,b,c}::Integer(1..3); ex := (n_{3})**2 n_{a}; canonicalise(_); ``` Result: `RuntimeError: Internal error in fill_index_position_map; cannot find index 1.` Sorry for so many issues. I'm trying to apply this program...

I really like the idea of working with formulas in small steps. But for this it is really important to read intermediate results. It would be good to have output...

Using two derivatives wih same object

2

``` \nabla{#}::Derivative; {A}::Depends(\nabla{#}); ex := \nabla{A}; unwrap(_); \partial{#}::Derivative; {A}::Depends(\partial{#}); ex := \nabla{A}; unwrap(_); ``` Result is 0 for the second `unwrap`. It looks like after `{A}::Depends(\partial{#});` the dependence on `\nabla`...

I am building Cadabra for Altlinux distribution now. There are a few changes which may be useful: - use PYTHON_SITE_PATH in c++ code, without rebuilding it in the same way...

The cadabra book says `Lines always have to be terminated with either a “;” or a “:”`. In cadabra2-cli 2.4.2 this works with expressions "a:=something", but not with algorithms. Algorithm...

dual MPSSE support?

I use the library with FT2232H chip ( http://www.ftdichip.com/Products/ICs/FT2232H.html ) which has two MPSSE interfaces. Now only one is supported in the library, IFACE_A is hardcoded here: https://github.com/devttys0/libmpsse/blob/master/src/mpsse.c#L59 I can...
