fix as.templatebrain.im3d

* spotted by check on r-devel
fix as.templatebrain.character
test templatebrain creation from im3d

* currently failing due to handling of regName
fix handling of regName and name arguments
BoundingBox should have class boundingbox
roxygenise
as.templatebrain set name & regName by default
Example/test setting name (but not short name)
Print short name as well

* I guess this is one of the most important fields
Clarify full and short names
