IAtomContainer now accessible in Java Snippets (trunk)

[swebb]

Hi All

It is now possible to interact with a CDKCell IAtomContainer with a Java Snippet (like the RDKit implementation). 

Example workflow:

Java snippet:

Table output:

Let me know if you run into any issues.

Known issue:

If you have another plugin that provides CDK then this may be put first on the classpath. As a result you can create your java snippet but when you got o execute you may get the following issue:

Known conflicting plugins:

• ChesMapper
• HCS Tools

If you uninstall these plugins the CDK Java Snippet functionality should work.
