simplified integral definition

Hi,

the code has just been updated to allow the following definitions of integrals:

integral_1 = { 'name' : 'i1', 'order' : 2, }

integrals = { 'i1' : 2, }

There are no more 'kind' keyword, and 'kind' attribute of Integral. They were removed because the integration kind is fully determined by the region topology.

The old versions

integral_1 = { 'name' : 'i1', 'kind' : 'v', 'order' : 2, }

integrals = { 'i1' : ('v', 2), }

still work for backward compatibility, but the kind is ignored and I recommend to remove it from your files.

Cheers, r.
