- Changed Model::singleStepBuild() to Model::addFromString() to create model elements; the latter requires explicit indication of element type (P/J/N/C)
- Removed old compatibility source (#ifdef MODEL_V1_COMPATIBLE) from f1->f0 converter and neuron definitions
|
-
Property svn:eol-style set to
native
