94   Neuro implementation - this object calculates the Neuron's state
95   (Neuro::state) in each simulation step.
96
97   SUBCLASSING TUTORIAL
98   ====================
99
100   1.Derive your custom neuron from NeuroImpl class. The name must be prefixed with NI_
101
102   class NI_MyNeuron: public NeuroImpl
103   { ... };
104
105   2.Public parameters
106   Create any number of public fields, they will be adjustable from the genotype level.
107   3 datatypes are supported: long, double and SString
108
109   public:
110   paInt intParameter;
111   double fpParameter;
112   SString txtParameter;
113
114
115   3.Required method: "instantiator".
116   It is always the same, just create a new instance of your neuron.
117   public:
118   NeuroImpl* makeNew() { return new NI_MyNeuron(); };
119
120
121   4.Required method: default constructor
122   Set the "paramentries" variable if you need public parameters in your neuron.
123   NI_..._tab is created automatically and should be declared as: extern ParamEntry NI_..._tab[];
124   At this stage the parameter values are not yet available.
125
126   public:
127   NI_MyNeuron() // no parameters!
128   {
129   paramentries=NI_MyNeuron_tab;
130   // you add here: some general initialization
131   }
132
133
134   5.Optional method: initialization
135   This method is called once before the neuron is actually used in the simulation.
136   The parameter values are already initialized (according to the genotype) and the neuron is bound to the creature (i.e. this->neuro is valid).
137   Return 0 if the neuron cannot be initialized.
138
139   int lateinit()
140   {
141   // you add here: initialization using full neuron context
142   // example: if (!neuro->joint) return 0; //this neuron must be attached to joint
143   return 1;//OK
144   }
145
146
147   6.Required method: simulation step
148   If it has output: calculate the next neuron state and call setState()
149   If it is an effector: do anything else
150
151   void go()
152   {
153   // you add here: things called every simulation step
154   }
155
156   Note: You can make your neuron fire before or after "regular" neurons by changing its "simorder" property (during initialization). The default value is 1, whereas receptors have simorder=0 and effectors have simorder=2.
157
158
159   7.Neuron definition
160   In order to incorporate the new neuron into Framsticks you need to provide some additional information (to be added to "f0.def" file).
161
162   NEUROCLASS(MyNeuron,MN,This is the name,`Neuron description',-1,1,0)
163   NEUROPROP(int,0,0,name of the int,d,,,,intParameter)
164   NEUROPROP(fp,0,0,name of the floating point,f,,,,fpParameter)
165   NEUROPROP(txt,0,0,name of the text,s,,,,txtParameter)
166   ENDNEUROCLASS
167
168   NEUROCLASS:
169   - MyNeuron: neuron class name (without the NI_ prefix)
170   - MN: neuron symbol (used in genotypes)
171   - full name and description
172   - -1: preferred number of inputs (special case: -1=any)
173   - 1: provides output: 1=yes/0=no
174   - 0: preferred location: 0=none, 1=part, 2=joint
175
176   NEUROPROP:
177   - int/fp/txt: parameter names as visible in genotypes and scripting
178   - "name of the ...": descriptive name
179   - d/f/s: type (int/floating point/string)
180   - intParameter/fpParameter/txtParameter: C++ field names
