Pycorrfit

- Second triplet time is now larger than first triplet time
by default
- Remove a hack that causes a run through all pages
e.g. when an average is created
- Bugfixes:
- Opening sessions with user-defined models
- Saving sessions with comments containing non-ASCII characters
- Windows build: Graphical plot export was misconfigured
(added matplotlibrc patch in .spec file)

- Bugfixes:
- Fixed minor wx sizer problems for the tools
- Fixed 'AttributeError' in page.py if no weights are present
- New confocal fitting models (111):
- 3D+3D, 2D+2D, 3D+2D; no triplet
- T+T+2D+2D, T+T+3D+2D; double triplet
- T+3D+3D+3D, T+3D+3D+2D (40, 59)
- Under the hood:
- Separation of core and GUI modules
- Include tests in distributions for PyPI
- Improve automated testing on Windows and Mac OS
- More constraint options for fitting

- Bugfixes
- Closing the batch control window causes segfault bug (142)
- Closing page causes error when batch control is active (143)
- Plot normalization causes "Save Session" to fail (144)
- Plot normalization not loaded from session (145)

- Batch control allows to select individual parameters (108)
- Allow to exclude pages from batch fitting (107)
- Bugfixes:
- Fix 'ValueError' in parameter display
- Possibly fixed error with 'yaml.safe_dump'
on Mac OSx 10.8.5
- Make sure background is lower than signal (137)

- Fitting: migrate to lmfit
- This introduces a new dependency for building PyCorrFit.
(e.g. in Debian, the package "python-lmfit" is required)
- Improved fitting behavior at parameter boundaries
- Removed "Polak-Ribiere" fitting algorithm
- Added "Sequential Linear Squares Programming" algorithm
- Heuristic fit (109):
- Detect parameters that are stuck during fitting
- Fit each curve five times or less and check
whether the fit converges.
- If two diffusion time parameter exist in a model, always
make sure that one parameter is the larger one. This
feature can currently not be disabled (110).
- Allow infinity ("inf" and "-inf") parameters for models
and boundaries.
- New model: confocal T+T+3D+3D
- Bugfixes:
- Sessions saved with 64bit Windows were not opened (136)
- Old sessions and "KeyError: 'chi2'"
- Old session file extension was not recognized (106)

- Bugfixes:
- "Slider Simulation"/"Parm Range" broken (133)
- Computation of average intensity did not work
correctly for unequally spaced traces
- Update .pt3 reader to version 8399ff7401
- Import traces of .pt3 files (experimental, 118)
Warning: Absolute values for intensity might be wrong
