Re-organize and improve current documentation

[nayraq80]

Some discussion has been generated at #146 around how regular users and developers can use current documentation, and some ideas came up from that discussion:

• This software is used by different user types
  • regular users, which only want to execute and use the application
  • developers, which want to contribute to the project.
• Regular users want to install this software as fast as possible
• Developers want to clone the repo and start developing as fast as possible
• Actually, the project documentation is dispersed in 3 source points: README file, Wiki and Front Page (manual)
• Some contents in the documentation are obsolete or duplicated

So, I would suggest to re-structure current documentation by following next steps:

1. Remove current Wiki, as it mainly contains obsolete information and interesting information can be moved to README and/or Front Page.
2. Re-organize current README and Front Page
3. Add new contents to documentation
4. Remove obsolete content from final documentation:
   • Wiki > Installation instructions > Binary packages
   • Wiki > Using Sun CC on Solaris
   • Wiki > Galleries and Examples

A proposal for a new organization for README and Front Page, including new contents, can be seen at Proposal for new organization of the documentation.pdf

What do you think about this?
