Added method to set which class to use to lookup resources
Added static strings for symbols in comparison nodes: public static final String SYMBOL = ".lt.", etc.

Moved src/test/java/org/lemsml/jlems/test/ParserTest.java to
src/test/java/org/lemsml/jlems/core/expression/ExpressionTest.java &
added some tests on powers & evaluating dimensionals
A number of @Overrides added...
initial q and d implementation of ast visitors for C, python (supposed to be easily extensible). This will be used to preparse eqs exported by org.neuroml.export
moved all visitors to org.neuroml.export. Needed ExpressionValued to implement IVisitable
Adding constructors for Unit and Dimensions and some helper functions
Improved handling of units with luminous intensity, j
added support for hyperbolic functions
Adding warning in build.xml & info on where to generate docs
Update README.md
Conditional example works in Pylems...
Readded option: -nogui, for running lems file (& saving results) without the graphics/plots
Tidied up & formatted standard examples after testing on PyLEMS
Merge branch 'master' into api

More verboste dumping of info from StateInstance on error

Formatting of code in QuantityReader & renaming useful functions e.g.
splitToMagnitudeAndUnit() for strrings like -60mV, etc.

Updated to v0.9.6.0 after merging changes from master into api branch of @tarelli
