/* more about command parsing:
grammer_parse(str) {
-> divide str into LH, RH, operation
-> operations & functions (e.g. +, .something()) call parsers WITHIN objects
-> variable assignments set up arrays with object pointers
}
automatically give each function a command method - that way being able
to create a connection automatically means specific connections can be
set
setting connection distribution example:
  # functions:
    distfuncab = probdist_numbydistance(20,1,0.6)
  # set selection:
    a = all[interneuron]
    b = all[principal]
  # connections:
    a.make_connections_with_distribution_function(b,distfuncab)
