Create executable to print summary information

[pgleeson]

There is a utility in pyNeuroML which can print the summary info in a NeuroML file, e.g. this file
https://github.com/NeuralEnsemble/libNeuroML/blob/development/neuroml/examples/test_files/simplenet.nml
with:

 pynml-summary simplenet.nml

prints:

*******************************************************
* NeuroMLDocument: simplenet
*
*   ExpTwoSynapse: ['syn0']
*   IafCell: ['iaf0']
*   PulseGenerator: ['input0', 'input1', 'input2', 'input3', 'input4']
*
*  Network: simplenet
*
*   10 cells in 2 populations 
*     Population: Pop0 with 5 components of type iaf0
*     Population: Pop1 with 5 components of type iaf0
*
*   16 connections in 1 projections 
*     Projection: Proj0 from Pop0 to Pop1, synapse: syn0
*       16 connections: [(Connection 0: 0 -> 0), ...]
*
*   5 inputs in 5 input lists 
*     Input list: il0 to Pop0, component input0
*       1 inputs: [(Input 0: 0:0(0.500000)), ...]
*     Input list: il1 to Pop0, component input1
*       1 inputs: [(Input 0: 1:0(0.500000)), ...]
*     Input list: il2 to Pop0, component input2
*       1 inputs: [(Input 0: 2:0(0.500000)), ...]
*     Input list: il3 to Pop0, component input3
*       1 inputs: [(Input 0: 3:0(0.500000)), ...]
*     Input list: il4 to Pop0, component input4
*       1 inputs: [(Input 0: 4:0(0.500000)), ...]
*

It would be useful if there was a similar executable cnml-summary which gets created when the NeuroML_API is installed (with sudo make install).

Ideally this will be faster than the Python version for large files... An initial parsing of the XML file can be seen here: https://github.com/NeuroML/NeuroML_API/blob/master/test/example.cxx#L21

Let me know if you've any questions @tuigimdochas

Note: source of Python summary is in here: https://raw.githubusercontent.com/NeuralEnsemble/libNeuroML/development/neuroml/nml/nml.py (summary() method).

There's also a similar method in Java here: https://github.com/NeuroML/org.neuroml.model/blob/development/src/main/java/org/neuroml/model/util/NeuroMLConverter.java#L309
