[gridoperator]
make postAssembly parameters templates, we don't want to impose certain GFS,
otherwise we can't reuse the same engine in different sub-assemblers
[gridglue]
fix constraints traints of GridGlueGridFunctionSpace
[gridglueoperator]
add missing methods to implement the full assembler interface
[gridglueoperator]
we currently assme that we are consistent, thus we don't need a borderDOFExchanger
[gridglueoperator]
fix paranoia check to ensure that we have consistent gridglue trial and test spaces
[test]
test gridglue bind for inside and outside
[test]
gridglue: test the creation of constraints
[test]
gridglue: add a dummy LOP and test creation of a gridglueoperator
[test]
print matrix type
[gridglueoperator]
implement loop over remote intersections and bind to the local functionspaces
... no assembly yet!
[test]
gridglue: try to create a matrix
