module naming #24
(modification agreed with Herve during his stay in Warsaw)

characters (and not cast from integer) #24

rule probing function in equidistant steps between ln(a) and ln(b) 

- Add layout scheme to match PARTONS 
- Apply current style
- Update doxyfile
   - update titles
   - update mathjax script
   - make it similar to PARTONS doxyfile

- Add .gitignore.
- Fix FindElementaryUtils.cmake.

In ALL (trunk):
- Improvements on the previous cmake commits.

In Elementary_utils (trunk):
- Add the installation routines in CMakeLists.
- Add doxyfile.

In NumA++ (trunk):
- Add the installation routines in CMakeLists.
- Add FindElementaryUtils.cmake module and adapt CMakeLists.

In NumA++_Tests (trunk):
- Add FindElementaryUtils.cmake & FindNumA++.cmake modules and adapt CMakeLists.

In PARTONS (trunk):
- Add the installation routines in CMakeLists.
- Add FindElementaryUtils.cmake & FindNumA++.cmake modules and adapt CMakeLists.

In PARTONS_exe, PARTONS_release, PARTONS_Tests, PARTONS_Fits (trunk):
- Add FindElementaryUtils.cmake, FindNumA++.cmake & FindPARTONS.cmake modules and adapt CMakeLists.

Adding simple cubic spline algorithm for NumA++

In NumA++:
- Correct the default absolute tolerance to 1e-3 in Integrator1D, instead of 0.

In NumA++:
- Correct the warning in DExp.

In NumA++:
- Initialize Eigen vectors to zero in LSMRSolver, to avoid random results (and maybe nan).

In PARTONS_Fits:
- Propagate changes in parameters names for DVCSConstantCFFModel.

In NumA++ (trunk):
- Removed the function solveLSMR in LinAlgUtils.
- New class LSMRSolver (using Eigen vectors and matrices for the computation).
- Removed old LSMR classes.
- Various conversions of stringstream to Formatter and runtime_error to CustomException.

In NumA++_Test (trunk):
- Propagation.

In NumA++ (trunk):
- Daniele's new DExp layer.

In NumA++ (trunk):
- New LSMR ported from scipy.

In NumA++ (trunk):
- Daniele's new DExp routine.

In ElementaryUtils (trunk):
- Change GenericType and Formatter precision to 16 instead of 17, to avoid messy numbers in formatting.

In NumA++ (trunk):
- Change some std::runtime_error to CustonException. A lot more to change...
- Time monitoring in LSMR.

In PARTONS:
- Inherit IncompleteGPDModule from GPDModule to be able to use GPDService. Lot of useless code commented.
- Some changes in Radon inversion modules...

In NumA++:
- Added -pedantic flag in CMakeLists for warnings.
- Moved LinAlgUtils to parent folder.
- Added LSMR iterative algorithm for sparse least-squares problems, taken from https://github.com/tvercaut/LSQR-cpp (APACHE licence) and adapted to fit into NumA.

In NumA++_Test:
- Added -pedantic flag in CMakeLists for warnings.
- Added test for LSMR also taken from github.

In PARTONS:
- Added -pedantic flag in CMakeLists for warnings.
- Converted one observable scenario to the new cross configuration.
- Various modifications and additions to the Radon Inverse files. Now, the DoubleDistribution modules are not needed anymore. It was too complicated to deal with... But it's still possible to use them I guess.
- Renamed the Radon Inverse daughter class because the brute-force approach was dropped in favor of a fixed number of rows for the matrix.

In PARTONS_exe:
- Added -pedantic flag in CMakeLists for warnings.
- Updated partons.properties to the new scheme.
- Added a test for the Radon inversion.

In PARTONS_release:
- Added -pedantic flag in CMakeLists for warnings.
- Added a scenario for GPD.
- Close PARTONS properly when exception.

In NumA++ (trunk) :
- Replace std::runtime_error by CustomException.

In PARTONS:
- Updates to Radon module

In NumA++:
- Remove blank files (created to avoid svn problem).
