Refactor specifiers a bit
Document the specifiers system and do some small name changes
(Index.all->Index.iterate_all)
Do not emit a warning on a namespace clash between a function and its
Function specifier counterpart.
Implement support for functions that exist in numpy and math.h (for C++
generated code)
Add the brian2.codegen.functions package to setup.py
Fix copy/paste errors, mapping arcsin and arctan to arccos.
Allow recording of static equations and do not crash for models without
differential equations.
Test the mathematical functions
Make sure to avoid circular dependencies. Make the clear() function more
robust.
Use numpy 1.6.2 for testing, 1.7.0 does not work with weave at the moment...
